After School Education Scope

There are many Pharmaceutical companies which need good Lab Technicians, you can apply for a job there. You can join a hospital, or nursing home as well. You can join as lab technician in colleges as well.

Career options after 10+2 depends on your subject if you're from PCM group than you can apply for B.Tech, Diploma in engineering, BCA, B.Sc, B.A., etc. but if you are from PCB group then you can pursue MBBS, nursing, pharmacy, biotech, B.Sc., B.A. Hons, etc. and if you're from commerce then you can only pursue BBA, B.Com or B.A.

Hi,
PCB does have a vast scope. All you need to do is, you should try and understand what exactly your FORTE is.
You can do a B.Sc, B.Com, BA, Business Management, in short what I want to say is, being an average student never stops you from taking a degree, except for the ones where Maths is compulsory (as you have taken PCB).
Class 12th matters a lot, but what actually matters in the end is your Master's Degree, your specialization. You can do Science and shift to various streams. The ocean is big, try diving near your goal.
