My Opinion
Decide whether you want to pursue higher education or get a job as soon as possible. If you choose higher education, and you enjoy studying and researching, consider aiming for a PhD in physics, chemistry, or mathematics.
If you want to get a job quickly, choose a course that offers good job prospects. It could be pilot training or preparing for CHSL or other government services (especially since the 8th Pay Commission is coming soon 😂 ).
I’m the second type of person. I enjoy studying, but only topics I’m passionate about—not book-based information or spending 10–15 years to earn a PhD degree.
