If you are not interested in Engineering, you can opt for pursuing a BSc course in Physics or Chemistry, depending upon your interest. You can go ahead and pursue a Master's and Doctorate degree if you want a career in academia. A degree in Physics or Chemistry is pretty flexible. There are many fields and jobs like in Healthcare sector, Medicine, Geographical and Geophysical sectors, Aerospace, Defense, Energy, Manufacturing, Telecommunications and even Finance and consulting. Other than these fields, you always have an option to choose the route of academia.

Hope this helps. Good luck.
