HI,

Nothing is impossible. All you need is determination and will to do a task. By this you will surely crack JEE advance in just 2 months.

The very first step is to get focused.Only a concentrated, industrious, and planned study plan will yield the desired score and rank.

Focus on improving your problem-solving speed, which requires continuous practice. Drill yourself with regular numerical problem practice. By the time you go for the actual exam

There are two ways to find practice problems and solutions: a good coaching course or books on all the three subjects.A good IIT-JEE coaching course will provide relevant topic-wise modules of questions and solutions. It will also set pre-planned time limits for completion to help you pace up yourself. If you can take a course and follow it religiously, 

As physics is most difficult for you, give more time for it and go for books which makes you understand better

following are some of the book 

Physics:

Concepts of Physics, Volumes 1 and 2, by H.C. Verma

Problems in General Physics, by I.E. Irodov

Fundamentals of Physics, by Halliday, Resnick, and Walker

Understanding Physics for JEE Main and Advanced (series), by D.C. Pandey

some tips which might help :

1. Solve at least 40-80 numerical problems daily.

2. Set time limits for questions.Practice to improve speed on problem-solving.

3. Start with the difficult areas first.Prepare brief notes on the hardest sections.

4. Prioritize by topic.Develop your strategy to prioritize your subjects in accordance to your requirements..

5. Analyze your mistakes.Find the points that you often face difficulty with and which slow you down.

6. Never quit until you have achieved daily target.Once you have solved your daily problems, make tomorrow's plan.

7. Practice logical thinking.Build your solutions step-by-step with contextual thinking. Discard stray thoughts.

8. Until the exam ends, don't give up.Keep up your routine and resolve to keep trying.

9. Use your board exam syllabus.Material from the board exams will be included on both JEE Main and JEE Advanced.

10. Consult test papers from previous years.Obtain copies of test papers from the past 10-15 years and solve the questions.

ALL THE BEST
