Science

Yes, you can. I was a Science student too. I took up pcme Physics Chemistry math, electronics) in my PUC/11th & 12th. Well. Not that I had a choice. My parents forced me into it since they wanted me to be an engineer and that just wasn't what I wanted to be. I had no interest whatsoever. However, I made sure to tell my parents how much I was forcing myself into this and that I wanted to do something I'd actually like without having to be forced to. Somehow with all that drama they agreed but clearly they weren't okay with this and made sure I wouldn't forget that everyday
I took B.Com accounts was new to me but I did pick up quick and I ended up liking to work on accountancy problems and so on and so forth. I didn't find it difficult like I did with Science, this just seemed so much better. So yes my point is you can do commerce after completing Science. But ONLY if YOU want to do it. Don't force yourself to do something you wouldn't want to do. :). .

The decision to pursue a Diploma after completing 10th standard or to complete 11th and 12th and then pursue a Bachelor's degree B.Sc. Depends on your interests, career goals, and academic aspirations. If you have a clear understanding of your interests and career goals, and if a Diploma programme can help you achieve them, then pursuing a Diploma after 10th standard may be a good option for you. Diploma programs usually have a shorter duration and provide practical training in a specific field, which can make you job-ready and employable in a shorter time frame. On the other hand, completing 11th and 12th and then pursuing a Bachelor's degree can provide you with a broader and more comprehensive education in a particular field. A Bachelor's degree usually takes longer to complete but can open up more career opportunities and provide a deeper understanding of the subject. Therefore, before making a decision, it is important to assess your interests and career goals, and then evaluate the pros and cons of each option. You may also want to consider factors such as the duration of the course, course curriculum, career prospects, and job opportunities before making a decision. Please upvote if it was helpful.
