what courses I can do with during b.sc.physics?
Hello,
I hope you are doing fine, Apart from your academics take part in all sorts of extra-curricular activities during the course. Take part in anything and everything that you think will give you some kind of exposure. If you have a subject/topic of personal interest that you want to pursue, get involved in it more. Be part of your local groups, volunteer for different kinds of programs and gain as much experience as you can.
There are several platforms online for you to do courses like MIT courseware, EdX, Coursera etc. There are free courses as well as paid ones that give you a formal certificate of completing the course. Again its good if you can do courses that will supplement your academics and also related to your interests.
I hope you find this information helpful. I wish you all the best for your future.
Good Luck
