Dear student,

Yes you can clear jee mains July attempt if you follow a proper study schedule. Firstly cover basic and important chapter like in chemistry -

chemical bonding, coordination chemistry, surface chemistry, chemical kinetics .... etc. which have high weightage and easy to score.

Further cover all three subjects equally solve Previous year question simultaneously with theory to save time and for getting better perspective of examination. Don't leave any one subject completely , atleast try to cover basic to moderate level theory.

Be consistent and patience you can clear jee mains.
