Consider helping! Please.

My boards have been significantly good im expecting a score of 250+/300 in PCM.

The main deal now is mht-cet, didnt prepare for jee had different plans but now this is my option B

Preparing for cet , ive been good in studies i studied the whole year but just board based.

There are 40 days left ( for the first attempt ) and ive started my prep ive been studying alot since the past 3 days , completed 2 chem topics , 1 math topic , 3 physics topics.

Cet is all i have as my option A is not in my hands now is it possible getting into top college ( mech branch ) ive filled the form for both attempts , by 2nd attempt can i get what i want? By preparing my as- off for the reamining days?
