Physics Spl

Hello,
I have passed class 12th (CBSE) in 2017. I suggest that you study NCERT but refer SL Arora as it will help you more. Go through the board papers of last 10 years and you'll be ready to score 90+ marks in physics (HSC).

Dear student,
I can understand your problem as a teacher.
Physics is not like a science-fi movie where the magic happens all the time. I recommend that you just focus on your studies and I strongly recommend that you should take help of some good teacher.

Best of luck.

No satisfying jobs. You have to do M.Sc for further opportunities.

For B.Sc physics, you should have chosen physics, chemistry, maths and any other subjects. You need to have a good score in 12th board exams. There is no particular cut off marks, they are determined by the admin only. You need to apply online or offline. For further details regarding admission refer:

If you belong to Tamil Nadu HSC board, then the applications for B.Sc courses are closed from 25th May.
Other board students (other state) can apply 3 days after the results of their respective boards.

If you find yourself very creative (in drawing and all) then go for B.Arch and if you don't have any interest in drawing stuff then I strongly advise you to not to opt B.arch as your career.
Between B.Tech and Physics honors, if you are getting admission in a reputed government college for B.Tech then keep your 1st option as B.Tech but, if somehow there are less chances of you getting a good college for B.Tech then you can keep physics honors from DU as an option.

You will have to wait till JoSAA 2017 website gets launched. You should check JEE Mains website continuously for notifications.

To get in any top college your score should be at least 85%. In Delhi University it's always above 95%. These cut offs are mainly for the general category. If you are in reserved category then some relaxation will always be there.
