I am in class 12 and want to crack neet exam 2020 as I also want to get good result in boards give me some tips.

Hello there!
You can ace your class 12th and clear neet as well . Both neet and class 12th board has some syllabus for PCB , the only difference is that board exam is subjective while neet is objective.  For board exam , you should complete ncert first , especially for biology and chemistry,  for physics you should revise formulas and  practice derivations again and again.  For neet , your focus should be on solving and practicing numericals. You should go through sample papers for board exams and you should must solve past 10 year questions as questions are quite repetitive in board exam .  You can create a list of important definitions, important formulas, important derivations in chemistry and physics and important diagrams in biology etc. and brush them up weekly. Set daily, weekly and monthly goals for yourself and try to accomplish them in the fixed time . Difficult topics must be studied thoroughly and wisely. Break lengthy chapters into topics and sub-topics to make learning easy. You can join a test series to keep an eye on your improvement. You can solve past year neet questions papers and you should go for mock test papers as well.
Thankyou
