Introduction
Choosing a career after completing 12th Science is one of the most crucial decisions in a student’s life. The Science stream is considered the most versatile because it opens doors to Engineering, Medical, Pure Sciences, Architecture, Pharmacy, Defence, Agriculture, and even emerging fields like Data Science and Artificial Intelligence.
Science students usually take either:
PCM (Physics, Chemistry, Mathematics) – Best for Engineering, Architecture, Defence, IT, Data Science.
PCB (Physics, Chemistry, Biology) – Best for Medical, Pharmacy, Agriculture, Biotechnology, Nursing.
PCMB (Physics, Chemistry, Maths, Biology) – Offers the flexibility to pursue both Engineering and Medical careers.
