The answer to the above question is definitely YES but with certain conditions.
Well, there is no hard and fast rule that coaching is mandatory for students preparing for NEET exam.
Nowadays since last few years pattern of the exam is almost 90% NCERT based which makes it easier for the students to score marks (although cut off goes high too).
Now our question should be how to qualify this tough exam and secure a seat in government medical College without coaching?
Look, first of all, you should start your exam preparation from your 11th standard and instead of focusing on tricks for solving questions, focus on improving and strengthening your concepts in all the 3 subjects(Physics, Chemistry and Biology).
Now, first of all let me tell you that i have cleared my NEET exam without coaching that too at the very attempt and I am currently a MBBS Student in one of the government medical College.
So I will share details on how to prepare for all the 3 subjects.
BIOLOGY
Learn and understand each and every line of NCERT. And then solve previous year questions, that will be enough.
CHEMISTRY
For organic and physical chemistry, go for standard books for concepts, you can also take help of YouTube lectures and for inorganic, just cram up NCERT. And then practice as many questions as you can.
PHYSICS
You should take help from YouTube channels for concepts and then solve H.C. Verma.
It will be enough.
So guys, these are the mantra to score a good rank in NEET exam without coaching.
