Physics Spl

You should go for KVPY SA exam is conducted for class 12th. KVPY SA exam will have single paper with objective type multiple choice questions. The duration of the paper is 3 hours. The paper will have negative marking. For KVPY preparation, NCERT books are best books.
Besides school books, you can use following books for reference:
1. Chemistry: P Bahadur for physical chemistry.
2. Solomons for organic chemistry.
3. OP Tandon for inorganic chemistry.
4. Physics: HC Verma Vol 1 and 2.
5. Mathematics: RS Agarwal, SL Loney.
6. Biology: NCERT.
Best of luck.

You have to get into a B.Sc. college, where you will be guided by your college faculty for your future perspective.
All the best.

You can become a scientist by an exhaustive study. It is what we call research. You try to assess your capacity for hard work and how you can increase it. Your work should be qualitative also. If you can be complete in your study, your work is finished. It is not just doing some job.

M.Sc honors is a four year integrated course after class 12th at BITS. Dual degree in BITS means that you can do another higher graduation degree along with M.Sc degree, e.g. M.Sc physics student can do B.Tech ECE as second / dual degree, simultaneously by choosing electives in M.Sc degree from B.Tech syllabus to reduce time period of second degree. In five to six years an average plus student can do both.

Based on market opportunities and scope, my recommendations in order of precedence for M.Sc students are electronics, physics and astrophysics.

Yes, there are courses on quantum physics and colleges like IISC - Bangalore, IIT-B, Tata Institute for Fundamental Research (TIFR) do offer such courses.

In my opinion, HC Verma is a sufficient tool for JEE mains and advanced. If you have a strong foundation, then solve problems from it. This will strengthen your concepts. However, if you want to make your fundamental clear, I would suggest you to refer some other good books like Pradeep or ABC.
All the best.
