I've just given the 10th boards in state board ( English version ) ..how will prepare for NEET ?

First of all you have to have science in class 11 with PCB ..
Always focus on you basic concepts. Don't mug up  anything.. Focus on Ncert textbooks for biology , physics and chemistry..practise on regular basis.. and don't overburden yourself with studies . Just enjoy your studies and have casual routine. And Do study daily and revise regularly..You will easily crack neet ug exam and aiims ug exam with good marks and rank.

Good luck..

Join your nearby coaching institute.
read NCERT word by word.
Solve past year type of problems.

and mostly FOCUS ON STUDIES WITH ADEQUATE SLEEP.
You can do it!!

Just take admission in science stream and start preparing for neet from ncert books as well as other reference from now.
All the best.
