According to me, first try to know the taste of career you are born with. Counsellors are available for this calculation.
You can go for leadership seed cultivation process training. After this, you will be sure what will suit you the best. It is only 6 weeks but it is worth it.

Marketing will suit more. But get counseling of any expert.

Nursing will place you better after the degree as it is always in demand and you may work abroad as well. If you have keen interest in research then go for B.Sc hons in biology, Botany or Zoology.

For job seekers b.pharmacy is good but B.Sc is great for researchers.

Hi
CE will give you a job where u have to sit for hours may be and design or repair software/hardware or programming etc.
Aircraft maintenance will most of the time keep you on your toes, be quick in making decisions and work as a team.
Decide as per your skill set and core strengths as jobs are there in both provided you are equipped well.

If you have inclination towards making a contribution to the agriculture sector, then B.Sc is the best option as you can actually be a researcher and work in govt sector. B.pharmacy will place you in hospitals, clinics or may be your own business.
So take a relook at your skills and what interests you more as both the jobs are well paying.
