how should i study from class 11 onward to become space researcher as professional .
Dear Aspirant,
As of now you should only focus on studying there is nothing specific you can do as of now to get a research study methotodoly, However, you should use books like HC Verma or Irodov, OP Tandon, RD Sharma etc books. These books are enriched with good problems that will help you nurture the problem solving and thinking habit which is very important.
Hope this helps. Thank you.
