How To Score High In JEE Main Chemistry Paper 2026?

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.

Hello, Based on the current date, the application process for both sessions of the JEE Main 2025 has already been completed. The exams for 2025 were conducted earlier this year.

You are likely asking about the upcoming JEE Main 2026 examination.

Based on the schedule followed by the National Testing Agency (NTA) in previous years, here is the expected timeline for the JEE Main 2026 application forms:

For the First Session (January/February 2026):

  • The application forms are expected to be released in November or December 2025.

For the Second Session (April 2026):

  • The application window for the second session typically opens after the results of the first session are declared, which is usually in February or March 2026.

Hope it's helpful to you.

Hello,

Yes, you are right; you can upload your class 10th marksheet for the JEE Main 2026 registration, as DigiLocker documents are considered equivalent to original physical documents by law. You should download the digitally signed marksheet from your DigiLocker account to upload it to the JEE Main application form.

I hope it will clear your query!!

Hello,

As of the JEE Main January 2026 session, candidates can no longer choose their preferred exam cities. Instead, the National Testing Agency (NTA) will assign your exam center based on the address linked to your Aadhaar card.

I hope it will clear your query!!

Hello,

Generally, UPES( University of Petroleum and Energy Studies) might have different admission criteria depending on the specific program. Some may require specific JEE Main scores, while others might consider alternative criteria like their own entrance exams (UPES Engineering Aptitude Test), merit in 12th grade or any other factors. Therefore, even if you didn’t qualify for JEE Mains, you might still be eligible for  certain programs at UPES. It’s best to check official UPES site for accurate admission requirements.

I hope this answers helps you!
