B.Com

Hi,
Maths is not compulsory to take admission in B.Com in human resource management. But do check with the college in which you want to take admission, as individual might have different eligibility criteria.

Hi Akash,
If you can manage time, then surely you can go for it. The interior design course is a regular course that demands your classroom attention and practical touch. Though there are some institutes that offer the course online and through distance learning, but it will not be that effectively successful. I would suggest you to take interior design at your Masters level if you are seriously interested in the course.

Hi,
Yes you are. But you need to clear their entrance exam as well i.e. OpenMAT.

Please refer to the link provided below for details on courses which you can select after completing class 12 in science. However, since you are a student of science, and you want to select a course from the commerce stream, you would have to select commerce as your stream. Good Luck!!
