Dear candidate... hope you're doing good..
Well, yes you may persue B.sc in physical sciences with computer science but may need a crash course in computer science before the graduation start. For this you may read class 12 cs books and may take a crash course online by some recognised organisation. You may also take the help of teachers as well as tuitions for the same.
Hope this helps you out.....
All the best:)
