I AM STUCK😭

So hey I am an icse 10th grader.. planning on giving neet..so rn my parents are rlly confused abt if they should pick iscs or CBSE for 11th and 12th..English ain't a problem for me..my current plan is joining allen online (11th) ik it kinda would be an extra workload..but I rlly don't wanna change schools..I am currently preparing for tht allen scholarship exam tht happens every october..I do have the determination to face it..but I am kinda scared tht wht if my decision to stay in isc along with neet fucks up both my 12th boards and neet😭
