Hello,

Yes, your granddaughter can join M.Sc Computer Science or MCA after completing her BCA final year .

M.Sc Computer Science Usually requires a B.Sc in Computer Science/IT or a related field, but some colleges accept BCA graduates too.

BCA graduates are fully eligible for MCA . Some universities may require Mathematics in 12th or Graduation .

She should check the specific college/university eligibility criteria before applying. Being from the BC category , she may also get reservation benefits in admissions.

Hope it helps !
