Should I start preparing for kvpy SA stream .I am presently in 10th and next year I will be 11th.if yes,then which books should I follow?
Is it good to start earlier or should I focus on boards only?
Focus more on class 10 NCERT as they will not only build your base but also help you in boards. Get class 11 NCERTs and read them in free time. Buy basic books like HC Verma. Rd Sharma, the subjective one and try.
Remember your main focus should be to be conceptually stronger in class 10 topics so that you can enter class 11 with full confidence.
