Scoring 95 plus percentile in JEE Main 2023 in 15-20 days is an ambitious goal, but it is possible with the right preparation and hard work. Here are some important topics that you can focus on:
Mathematics:
Calculus (especially limits, continuity, differentiability, and application of derivatives)
Algebra (especially complex numbers, quadratic equations, and permutations and combinations)
Coordinate geometry (especially straight lines, circles, and conic sections)
Physics:
Mechanics (especially Laws of Motion work-energy-power, and rotational motion)
Electromagnetism (especially electrostatics, Current Electricity and electromagnetic induction)
Optics (especially wave Optics and ray optics)
Chemistry:
Organic Chemistry (especially general organic Chemistry and hydrocarbons)
Inorganic Chemistry (especially periodic table and chemical bonding)
Physical Chemistry (especially Thermodynamics and equilibrium)
Remember, these are just some important topics, and you should also revise the topics that you are already comfortable with. Additionally, it's important to solve as many JEE Main previous year question papers and mock tests as possible to understand the exam pattern and the type of questions asked. All the best for your preparations.

To score 98 percentile in JEE Main 2023, you will need to have a strong grasp of the following topics:
Mathematics:
Algebra (quadratic equations, progressions, permutations and combinations, etc. )
Trigonometry (identities, equations, Inverse Trigonometric Functions etc. )
Calculus (differential and integral calculus, limits, continuity, etc. )
Coordinate geometry (lines, circles, Conic Sections etc. )
Vectors and 3D geometry
Physics:
Mechanics Laws of Motion work, energy and power, Gravitation etc. )
Thermodynamics (heat and temperature, laws of Thermodynamics etc. )
Electricity and magnetism (electric charges, electric fields, capacitance, magnetic fields, etc. )
Optics (reflection and refraction, wave Optics etc. )
Modern Physics (atomic and nuclear Physics etc. )
Chemistry:
