Hi,

With a degree in bsc in life sciences you can do jobs in some private companies like of fertilizer, medicine etc. Or you can apply for a government jobs.

With job I you want to do study then you can do distance learning courses.  So that side by side both job and study continues.

If you want to do study in regular mode then you have to search for part time jobs suitable to your credentials.

Hope this helps. All the best.
