Hello there

No. You can't decide the combination itself. Life science is already a subject that has a combination of three subjects that are Zoology, Botany and Chemistry. You study all the three subjects together. Life science students get a broad of view of all these subjects together.

In every semester, you are introduced to an additional subject that can be evs, english or zbc (Zoology, botany, chemistry) related.

You can't choose the subjects on your own. The syllabus and subjects are already prescribed by the University itself.

Thanks
