I passed my 10th in private what is best degree to do

After 10th there is no degree courses but diploma and ITI courses. After 12th only you can apply for degree courses. You can study further and can complete 12th from either regular or private. But I would suggest you to study in regular it will be helpful if you want to pursue degree courses further in future. After 12th you can do any degree course such as b.com, BBA, BTech, BE, professional courses etc. It's upon your interest and subject chosen, if you want further information you can ask.
