Hi,

Yes, it is possible with extreme hard work, but you must put in a lot of effort. If you look at the question paper, you will notice that math is the most difficult section, which is why I say it is difficult to get an 80 in two months starting from the beginning. For your first attempt, aim for around 50 marks and focus on only a few chapters. The amount of time you need to prepare for JEE Main is entirely dependent on your own abilities. If you are dedicated enough, you should be able to crack JEE Mains in the remaining time. considering the remaining time for JEE, it would be possible with extreme hard work. Divide the subject topics into days and begin following them. Investigate qualitatively.

Below given are some of the Tips which you can follow for better preparation of JEE MAIN in one month

1. Get the JEE MAIN 2022 syllabus and exam pattern.
2. Prefer the best book including NCERT
3. It is not a good idea to start with a new topic when there are just 1 month remaining before the exam. Revise the topics that you have studied from your old notes.
4. Focus on the chapters that are most important and the areas you are weak
5. In case you have any doubts, get your queries resolved at the earliest
6. Revise the important points for all the chapters of all the subjects. Revise all the important formulas for Mathematics and Physics.
7. Solve as many  Previous year paper as possible and give mock test at regular basis.
8. Make sure you do not waste your time.

Hope this helps.

Good luck.
