JEE Main 2015 Question Paper Code A

Preparing for the JEE Main in just 30 days is a challenging but achievable task if you follow a highly disciplined and strategic approach. According to the Careers360 30-day study plan , the key is to shift your focus from learning everything to mastering high-weightage topics and practicing rigorously.

Phase 1: Week 1 & 2 – Focus on High-Weightage Chapters

During the first 15 days, prioritize topics that frequently appear in the exam.

• Physics: Modern Physics, Heat & Thermodynamics, Optics, and Current Electricity.

• Chemistry: GOC (General Organic Chemistry), Chemical Bonding, p-Block elements, and Solutions.

• Maths: Matrices & Determinants, Sequences & Series, Coordinate Geometry, and Vector & 3D Geometry.

• Study Strategy: Use NCERT for Chemistry and simplified notes for Physics/Maths. Spend 3-4 hours on each subject daily.

Phase 2: Week 3 – Revision and Formula Memorization

• Short Notes: Go through the short notes you made during the first two weeks.

• Flashcards: Use flashcards for inorganic chemistry reactions and physics formulas.

• Mock Tests: Start giving one full-length mock test every alternate day. Analyze your mistakes immediately to avoid repeating them.

Phase 3: Final Week – Full Simulation and Relaxation

• Previous Year Papers (PYQs): Solve the last 3-5 years of JEE Main papers in the actual exam time slot (9 AM–12 PM or 3 PM–6 PM) to sync your body clock.

• No New Topics: Stop picking up new chapters. Focus solely on what you already know to build confidence.

• Accuracy over Speed: Focus on getting the questions right rather than attempting all of them, as negative marking can significantly lower your percentile.

Hello,

If you filled the JEE Main January form with Class 12 passed in 2025 and are planning to appear again for the Class 12 exam through HOS, there is usually no serious issue. You were eligible to apply since you had already passed Class 12. Reappearing through HOS for improvement or requalification is allowed, provided HOS is a recognized board. During counselling, your latest valid Class 12 result will be considered. Make sure you meet the 75% marks or top 20 percentile requirement where applicable. If a correction window opens, update details if needed.

Hope this has solved your query. Thank You.

The marks needed for a 99+ percentile in the JEE Main January attempt depend on the difficulty of the paper and the total number of candidates. Generally, you need roughly *180–200* marks out of 300 to hit the 99+ percentile. The exact cutoff varies each session, so checking the official NTA percentile score calculator or previous year cutoffs gives a more precise idea.
