Dear candidate yes, if you receive a better seat after MHT CET betterment round then the amount that you have already paid for round 2 would be adjusted accordingly. They will refund you the money but it may not be the entire money, some amount would be deducted as a processing charge. But for certain confirmations I would ask you to always be confident and then only select a good Institution. Follow the information brochure of the Institute allotted to you, and know their refund policy.

Good luck!!
