Hello dear

No won't get admission to the dummy school without clearing your 11th. So it's my request you, first of all, repeat your 11th or either take admission in 11th std of dummy school.

Dummy school is all about the entrance exam if you want to focus on your competitive exam so you take admission that you will get more time. but if you wanna do bsc then join a normal college and focus on your study so you will get a good percentage on boards.

I hope this will help you

Good luck
