No, you can't apply for class 11. After you get the result of class 10 annual exam ,you should  definitely try it . Depending on your number you should applied in class 11(science).

Hello zamir,

Hope you are doing well!

You can't apply for fyjc without clearing 10th. Once you will clear 10th then you can go for 11th.

I hope this helpful for you.

Best wishes! !
