I don't know anything about admission process of NEET. Iam going to write NEET in 2020. So please help me out . What is the admission proces

Thank you so much , madam

Mention not.I would greatly advise you to join some coaching institute (if you can afford).And if you don't want to join coaching, no worries. You have to study hard and aim for score above 570+ out of 720 marks for NEET.Below, I am mentioning some links for the cut offs for NEET, AIIMS, JIPMER, KARNATAKA for reference so that you could get some idea how much marks and ALL INDIA RANK needed for particular colleges.https://medicine.careers360.com/articles/neet-cut-offhttps://medicine.careers360.com/articles/aiims-mbbs-cut-offhttps://medicine.careers360.com/articles/jipmer-cut-offhttps://medicine.careers360.com/articles/neet-cutoff-karnataka

and also practice previous years questions which are easily available in marks and also some JEE mains questions too.

I have joined Coaching & Iam giving my best.
Will u please suggest me some good books ?

As I am unaware about your coaching. If they provide good supplements for all the subjects then refer them and also the NCERTs are very much important for biology and chemistry, make sure you start with it for bio and chem although for physics, NCERT is not good to start with. And also the NCERT exemplar for all three subjects for solving and practising.For physical chemistry, refer book N Awasthi after NCERTFor organi chem, Himanshu Pandey after NCERTFor inorganic chem, practise as much as question possible from NCERT and coaching materialsFor physics, start with Evergreen and then refer books like HC Verma and do exercise questions in NCERTKindly note that the NCERT is core for BIOLOGY and CHEMISTRY and the exercise questions for PHYSICS.Keep giving mock test for particular chapters after you have studied them also some JEE mains questions too. and also keep revising them regularly as most of students don't do that which lead to forgetting the studied things.The only books is NCERT, NCERT, NCERT then if you are sure enough that you have good hold on them then only move to mentioned books.
