IISER Preparation Tips 2026 

The IISER 2026 preparation will require a strategic approach focused on solid conceptual clarity, effective time management, and practice to excel in the competitive exam. With four subjects—Physics, Chemistry, Mathematics, and Biology—candidates need to prioritize their strengths while ensuring balanced preparation. The following is an extended article outlining effective preparation tips to assist IISER 2026 aspirants.

Understand the IISER 2026 Syllabus and Exam Pattern

• Start with a thorough study of the official syllabus based on NCERT Class XI and XII curricula for Physics, Chemistry, Mathematics, and Biology.
• Familiarity with the exam pattern—60 questions split equally across subjects, 4 marks for correct answers, and negative marking for wrong ones—is critical to strategize preparation.
• Knowing that candidates generally need to qualify by scoring in any three of the four sections can help prioritize subjects according to strengths.

Stick to NCERT Textbooks as Primary Resources

• NCERT is considered the best source for conceptual clarity and covers the exam syllabus comprehensively for all subjects.
• Students should focus on understanding concepts deeply by solving back exercises and exploring example problems in NCERTs before referring to other resources.
• For Mathematics and Physics, practice is key, including solving derivations and numerical problems.

Regular Practice and Mock Tests

• Daily practice of 30-40 MCQs from past papers or similar question banks builds speed and accuracy.
• Weekly full-length mock tests simulate exam conditions and help identify weak areas to focus on in subsequent weeks.
• Time management skills are sharpened by timed practice tests, which is important given the exam's three-hour duration.

Focus on Strengths and Strategize Subject Choice

• Since IISER allows merit calculation based on the best three subjects, aspirants can choose to emphasize their stronger subjects.
• For instance, candidates strong in Math and Physics may allocate less time to Biology and vice versa. However, holistic preparation is advisable.

Revise with Short Notes and Visuals

• Creating concise notes of formulas, key concepts, and common mistakes from practice sessions enables efficient last-minute revision.
• Including diagrams, charts, and mnemonics can enhance retention.
• Start regular revision sessions at least two months before the exam, increasing frequency closer to the date.

Use Quality Additional Resources and Online Platforms

• Trusted online platforms offering video lectures, doubt-clearing forums, and test series can supplement self-study.
• Avoid cluttering preparation with too many sources instead pick a handful of trusted materials.
• Joining short-term crash courses or coaching (online/offline) may benefit those needing structured guidance.

Maintain Physical and Mental Health

• Regular physical exercise, adequate sleep, and stress management techniques such as meditation or hobbies help maintain focus and stamina.
• Staying motivated through peer discussions, mentors, or study groups can be encouraging.
