sir im in 11 i have taken a commerce what should i take in optional subject maths or computer
If you want to pursue Commerce in future then I would recommend you to take Mathematics as a subject in 10+2 because many colleges have the eligibility criteria that a student must have Mathematics in 10+2 in order to get BCOM or other courses like BMS etc. Also this choice can help you to pursue higher education in the field such as CA, Costing, Accountancy, Applied Data Analysis, Financial Engineering etc.
So if you wish to go in further studies with commerce then Mathematics will be the best.
