Hello dear student,
Yes definitely you can do bsc and you don't need to attend a class . For that you want to take admission in colleges who provide open or distance learning. There are universities like IGNOU and Delhi university. There must be many more like them . It's good to do from a recognised university unlike from anywhere which has not even a value .I hope this was helpful and you understood. For any further questions and for any further information please feel free to contact anytime.
Best wishes
