1. Understand the Syllabus and Topic Weightage
Before you start preparing, get a clear idea of the entire JEE Main Chemistry Syllabus. Identify which topics carry more weight and are frequently asked in previous exams. This will help you prioritize and plan your study effectively.
2. Make a Study Plan
You have to make a daily study plan that has all the subjects of JEE Main. It should have time for revision, mock tests, and also include short breaks in it to avoid exhaustion. A well-prepared plan will help you stay focused and consistent.
3. Begin your preparation with NCERT textbooks
Begin your preparation with NCERT textbooks of Chemistry for Classes 11 and 12, as they cover fundamental concepts and frequently asked questions in JEE Main. Once you’re confident, move to advanced reference books like O.P. Tandon for Physical, Organic, and Inorganic Chemistry, and Morrison & Boyd for Organic Chemistry to strengthen your understanding and problem-solving skills.
4. Practice Previous Year Papers (PYQs)
Do practice at least 10–12 years of JEE Main question papers. This is beneficial for you to understand the pattern, difficulty level, and most repeated question of JEE Main exam.
5. Take Mock Tests Under Exam Conditions
Create real exam Situations with mock tests. Check mistakes, and maintain a notebook to note down errors and then do improvements.
