Hello dear student,
Yes it will be helpful right now you are in 11th standard try to learn and try to gain deep knowledge of your subjects. Because when conceptual questions comes in NEET then usually students are not able to solve them.  So don't worry you have chosen the right way and try to devote maximum tie.ti your studies. Try to solve MCQ's when you complete a topic or a chapter that will help you increase your ability to solve questions in time and with logics . I hope this was helpful
Best wishes
