Hi Shruti,

First of all, congratulations on your GMAT score of 720. I suppose your question pertains to joining the CAP round using your GMAT score as you haven't filled up the MAH CET form. You have to fill up a form of DTE CAP 2019 for that. The registration will begin in May 2019. You have to fill up the online application form, after which you will be called for their GDPI round and further process.

Your GMAT score will be used for the allotment of seats in Provisional allotment of CAP round I, II and III. 

Kindly note - If you are aiming for the top B-schools in Maharashtra then you might be asked to register for their CAP round around 15 May. So please keep a check on that.

Let me know if you need further clarifications.
