Welcome to the SOF International English Olympiad (IEO) 2025–26. This annual English competition, organized by the Science Olympiad Foundation, is a golden opportunity for students to sharpen their language skills and shine on a global stage. Every year, millions of students from thousands of schools participate in the IEO and other SOF Olympiads, a testament to how prestigious and beneficial this exam is. Not only does IEO boost students’ confidence and linguistic prowess, it also looks great on academic resumes and even offers scholarships for multiple categories. Teachers and parents love it too, as it encourages critical thinking, creativity, and a lifelong love for the English language.
In this blog post, we’ll cover everything students and parents need to know about the IEO 2025–26. We’ll start with a quick rundown of the exam format, then dive into useful vocabulary and grammar hacks for tricky topics (homophones, tenses, phrasal verbs, sentence correction, idioms, and more). Finally, we’ll share actionable preparation tips to help you practice effectively. Let’s get started on the journey to IEO success!
IEO 2025–26 Exam Format and Structure
Before jumping into study tips, it’s important to understand how the IEO exam is structured. The IEO is a 60-minute exam consisting of multiple-choice questions. All students from classes 1 to 12 can participate (the Olympiad is held at two levels – Level 1 for all participants, and Level 2 for high scorers in classes 1–12). Here’s a brief overview of the Level 1 exam pattern:
-
Total Questions: 35 questions for classes 1–4, and 50 questions for classes 5–12.
-
Time Limit: 1 hour (60 minutes).
-
Question Type: Objective multiple-choice questions only.
-
Sections: The paper is divided into four sections:
-
Word and Structure Knowledge – vocabulary, grammar, and word usage
-
Reading – comprehension passages
-
Spoken and Written Expression – situational dialogue and sentence completion
-
Achievers’ Section – higher-order thinking questions (more challenging, carrying extra marks per question)
-
For example, a class 5 student’s paper will have 45 questions across sections 1–3 and 5 “Achievers” questions, making 50 total. Achievers’ Section questions are worth more points (to reward advanced skills). The Level 2 exam (for those who qualify) follows a similar pattern but with only three sections (Word & Structure, Reading, and Achievers).

What’s the syllabus? The IEO syllabus aligns broadly with what students learn in school (CBSE/ICSE and state boards), but the questions often twist these concepts to test practical understanding. The focus is on effective communication and usage of English, not just rote grammar rules. In other words, memorizing grammar is not enough; students must know how to apply concepts in real situations. Knowing the exam pattern and syllabus thoroughly is the first step to success.
Common Tricky Areas and Hacks to Master Them
Even good English students stumble on certain topics in the IEO. Let’s explore some tricky areas and hacks to tackle them. Teachers can use these insights in the classroom, and students can apply them in practice sessions:
-
Homophones & Confusing Words: English is full of words that sound alike but have different meanings and spellings – and these often trip students up. Classic examples include affect vs. effect, than vs. then, which vs. witch, hear vs. here, buy vs. by, weather vs. whether, and so on. To master homophones, always look at context. If you’re stuck, ask yourself: “Which meaning fits here?” For instance, “There is a book on their desk.” – there (a place) versus their (possessive). Make flashcards of common homophone pairs with example sentences. A neat trick is to learn mnemonics for each word (e.g. remember “affect = action” (verb) vs. “effect = end result” (noun)). With practice, you’ll instantly recognize which spelling makes sense by the sentence’s meaning.
-
Taming the Tenses: Many students struggle with verb tenses – using the wrong tense or inconsistent tenses in a sentence. It’s such a common issue that mixing up present and past tense tops the list of frequent English errors! To get tenses right, pay attention to time clues in the sentence (e.g. “yesterday” calls for past tense, whereas “currently” suggests present continuous). Keep your subject-verb agreement in mind as well – if the subject is singular, the verb needs the proper singular form in present tense (say “He goes to school” not “He go to school”). A good hack is to practice timeline charts: write a timeline and place verbs in past, present, future to visualize their forms. Also, watch out for irregular verbs (go/went/gone, sing/sang/sung, etc.) – these just need memorization. Consistent review of tense tables and doing exercises will make choosing the correct tense feel natural.
-
Phrasal Verbs Made Simple: Phrasal verbs (verbs followed by a preposition or adverb, like look after, give up, turn on) are everywhere in English – and yes, they appear in IEO questions. They can be tricky because their meaning isn’t always obvious from the words (to “turn up” can mean appear, while to “turn down” means refuse or lower volume). Don’t panic! Treat each phrasal verb as a new vocabulary word to learn. Group them by a common verb or particle to make connections (for example, list out all the phrasal verbs with “get”: get up, get out, get along, get over, etc., or all those with “out”: break out, figure out, carry out, etc.). Use them in your own sentences – the sillier, the better, so you remember them. Flashcards can help here too: on one side write “give up” and on the other “to stop trying – e.g., I won’t give up on my dreams.” Learning phrasal verbs in context (through stories or examples) is more effective than just memorizing definitions.
-
Sentence Correction & Grammar Gems: The IEO often has questions where you must spot an error or choose the best way to rewrite a sentence. These test your grasp of grammar nuances. Common traps include pronoun agreement, subject-verb agreement, and punctuation misuse. For instance, watch out for pronouns that don’t match their noun: “Everyone did their best” is technically wrong because “everyone” is singular; it should be “Everyone did his or her best.”. Also, be careful with possessives and contractions: its vs. it’s is a classic example – “The dog wagged its tail” (possessive its, no apostrophe) versus “It’s (it is) time for dinner”. Hack: Whenever you see an underlined portion or multiple-choice options for a sentence, mentally check for these common errors first – is the subject matching the verb? Is the tense consistent? Is the punctuation correct? Eliminating obviously wrong options using these checks can quickly narrow down the answer. Teachers can help students practice by giving daily one-sentence correction challenges. Over time, you’ll develop an instinct for spotting what “sounds wrong” in English usage.
-
Idioms & Proverbs (Figurative Language): Idiomatic expressions can be the dark horse of the English Olympiad. An idiom is a phrase that doesn’t literally mean what it says – for example, “break the ice” means to start a conversation, not actually smash ice. The IEO may incorporate idioms or proverbs into questions to assess your understanding of their true meaning. The best way to master idioms is to learn them in context. Read stories, dialogues or even comics – note down quirky phrases you encounter. If you see “Spill the beans” in a sentence, even if you’ve never heard it before, look at the context: “She spilled the beans about the surprise party.” You might guess it means to reveal the secret. There are plenty of lists of common idioms; try learning a few each week and using them in your speech or writing (maybe drop one in conversation with your teacher – if they smile, you probably used it correctly!). Pro-tip: Don’t interpret idioms word-for-word. Instead, think “What message is this conveying?” If unsure, eliminate options that take the idiom literally. This skill comes with practice and exposure to lots of English usage. Teachers can make it fun by having an “Idiom of the Day” on the board for students to explain or act out.
By focusing on these areas and practicing them regularly, you’ll gain a huge advantage in the actual exam. Remember, the IEO isn’t just about memorizing definitions or rules, but applying your knowledge. As the SOF exam guidelines emphasize, a solid understanding of grammar and vocabulary, along with their proper usage, will help you score top marks. Now that we’ve covered what to study, let’s talk about how to study effectively.

Top Preparation Tips for IEO Success
Whether you’re a student aiming for a top rank or a teacher guiding your class, these preparation tips will set you on the right track. Feel free to adapt them to your schedule and learning style – consistency and smart work are the keys!
-
Understand the syllabus & exam pattern: Begin by reviewing the official IEO syllabus and pattern for your class. Knowing the weightage of each section helps you prioritize. Teachers can discuss the exam structure in class so students know what to expect – for example, that there will be vocabulary, reading comprehension, etc., and higher-order questions in the Achievers’ Section. Clarity on the format means fewer surprises on exam day.
-
Start early with a study plan: Don’t wait until the last minute. Plan out your weeks leading up to the Olympiad. Allocate time for vocabulary, grammar, reading practice, and taking mock tests. A balanced schedule might include, say, 30 minutes daily for grammar/vocab and an hour on weekends for sample papers. Sticking to a regular study routine (with short breaks to avoid burnout) will cover all topics without stress. Consistency is crucial – a little bit of practice every day beats cramming in one go.
-
Learn 5 new words every day: Make vocabulary-building a daily habit. Commit to learning at least five new English words each day. You can pick words from your reading, from vocabulary books, or even from an app. Write down each word with its meaning and use it in a sentence. For example, if you learn “prototype”, note: prototype – a first model of something. “We built a prototype of the robot.” Revisiting these words at the end of the week helps transfer them to your long-term memory. Teachers might encourage a “word of the day” in class – by exam time, students will have a hefty vocabulary bank to draw from!
-
Read a lot (and widely): There’s no shortcut here – extensive reading dramatically improves your understanding of grammar in use and exposes you to new words. Try to read English for 15–20 minutes daily. What to read? Anything you enjoy: storybooks, children’s magazines, newspaper articles, blogs for kids/teens, etc. Reading not only builds vocabulary but also shows you idioms, sentence structures, and writing styles in action. It passively fine-tunes your grammar “ear”. Teachers can help by maintaining a small reading corner or library and giving students short, interesting passages with questions (to practice comprehension for the exam).
-
Make learning fun and engaging: English is not a subject you memorize; you get better at it by using it. Find creative ways to immerse yourself in the language. Love movies or cartoons? Watch them in English with subtitles. Try speaking in English with friends or family about your day. Participating in school activities like debates, elocutions, essay writing, or Spell Bee competitions indirectly prepares you for IEO by improving your fluency and confidence. Teachers can incorporate fun language games, like quizzing homophones or idioms, so students learn playfully. When learning is enjoyable, you’ll be motivated to practice more (and fear English less!).
-
Practice with sample papers and mock tests: Practice, practice, practice! Work through IEO sample papers and previous years’ question papers to familiarize yourself with the question style. Set a timer for 60 minutes and attempt a full paper in one go. This builds stamina and exam temperament. After each test, check your answers thoroughly. Identify where you made mistakes: Was it a specific grammar rule? A new word you didn’t know? Use these insights to focus your study further. Taking at least a few mock tests will also train you in time management, so you don’t end up with unanswered questions due to slow reading. It’s reported that many students initially struggle to finish on time, and practice is the cure for that. Treat mock exams as learning tools – each one will make you better, so by the time the real exam comes, you’ll feel ready and confident.
-
Review and refine your grammar: As the exam nears, spend time revising key grammar points that often appear in IEO. Make a checklist: tenses, parts of speech, subject-verb agreement, pronoun usage, conditionals, reported speech, etc. Solve targeted exercises for these. If certain error types keep tripping you up (maybe you still confuse “much” vs. “many” or forget the article in front of a noun), zero in on those. There are plenty of grammar workbooks and online quizzes you can use for extra practice. Teachers can hold quick revision drills in class, like a rapid-fire round of grammar questions, to keep students on their toes.
-
Stay consistent and positive: Lastly, remember that improvement in language is a gradual process; consistency and a positive attitude are key. Encourage yourself (and as teachers, encourage your students) to speak, write, and think in English regularly. If you make mistakes, it’s okay – that’s part of learning. Leading up to the exam, maintain a healthy routine: adequate sleep, short breaks during study, and some relaxation. A calm, rested mind absorbs knowledge better. On exam day, trust your preparation. Even if you encounter a tough question, don’t panic. Use elimination strategies and your understanding of English to make an educated guess if needed. Often, your language intuition – built through all the reading and practice – will guide you to the correct answer.
