Hi,
     Yes definitely. Management quota means - you will get admission by donation of which all the procedure is maintained by the college management itself. Every private college has 10% seats under Management Quota, so donation is compulsory if you no are taking admission through your merit rank.

Now, donation varies college to college. Which college has the big reputations & demanding, their donation will be high. Now, how much the donation will be, how much you should have to pay etc those kind of things only can tell the college, where you are taking admission through their management quota. The management quota donations decided by college itself. Donation also depends on your 12th results, your entrance merit rank etc. If your marks is good then you have to pay less donation or you you have to high.
