Science

See if you want to go for the Basic Sciences, then I would say just after B.Sc. There are not many job profiles available but if you complete the M.Sc. Course, then you have ample opportunities in both Industry & Academic sectors. IF YOU GO FOR THE PARAMEDICAL COURSES (the jobs are higher here), THEN Some of the subjects you can study in your B.Sc. Are:
NURSING (THIS HAVE GOOD JOB PERSPECTIVE AFTER B.Sc)
B.Sc IN MEDICAL IMAGING TECHNOLOGY
B.Sc IN OPERATION THEATRE TECHNOLOGY
BPT (Bachelor OF PHYSIOTHERAPY)
If you want to go for Pure scientific portions of Biology then you need to do an M.Sc. To get good chances. Some of the courses with good perspective in the Jobs & Academic sector:
B.Sc GENETICS
B.Sc BIOCHEMISTRY
B.Sc MICROBIOLOGY
B.Sc ZOOLOGY
B.Sc BOTANY
B.Sc BIOINFORMATICS
B.Sc IN MARINE BIOLOGY
I hope this helps. Wish you a very productive eve!
