Hey!There

11th results doesn't matter soo much.If you have interest in that stream then you can ignore 11th results overall stream matters.Do focus in main papers like in PCM/PCB in Science stream.Aslo,you might have interest in other stream then you can can change stream as it is perfect time for that.Don't think about 2nd option Soo much if you chosen stream  as per your interest..

Ask if any query.

Hello there. I would like to tell you that you do not have any option other than repeating 11th class if you fail. There are many schools which takes compartment exams for students who have failed in few subjects. But if your school does not consider compartment exams, then you have to repeat 11th class.

I hope you found this answer helpful. Good luck for your future.
