Hi shanky,

Obviously you can get 330+ marks in physics and chemistry combined in NEET.
All you need is to follow these steps

1.Learn from a fixed teacher: It does not matter if you are studying using Youtube lectures or a paid coaching. Find a teacher according to your style. Stick to your teacher, trust him/her. Do not change teacher in between.

2.Make your own notes: Do not try to use another persons notes, or downloadable pdf or anything. Make your own running notes in class. Revise the topic you learned using those notes on the same day.

3.Give NCERT paramount importance: You must know that almost every question in NEET comes from NCERT irrespective of the subject. Do not leave any line, solved example or exercise of NCERT practice them thoroughly and multiple times.

4.Practice more and more MCQs: You must give 50-50 time to theory reading and MCQ practice. You will have to train yourself so that whatever type of MCQ comes, you can handle it.

5.Dig at one place, dig deeper: Do not go for so many books. For theory NCERT is more than enough. For physics and Chem chose one good book and practice it twice instead of going for two different books.

If you follow these steps, I am sure you will get your dream college AIIMS DELHI.

I wish you good luck in your NEET PREPARATION journey.
