what do you suggest, for xi standard , is better to go for bifocal ?? also which subject would be better computer science or electronicas ? thanks for your guidance

Dear vinod,

Its good if you are preparing for competition exams along with your 11th. make your concepts clear by studying the basic books..then you can start solving from standard books say Arihant...

Computer science is preferred by most of the students but it all depends on the interest of a student.
