try to understand the reactions. If u r trying to learn them, u will not be able to remember them. read them deeply and I m sure that u will be successful. even then if u want to learn any topic, make some stories related to that and it will be helpful to u
I think u can easily learn up the rx(s) of ur textbook NCERT just by understanding. Secondly, u may write down them all in a paper and revise it whenevr possible!
reactions don't try to remember. If you want to mug up then try writing them 2-3 times of your own without seeing the book. Correct if wrong and when you get the correct one then write it 2 more times.
even then if u want to learn any topic, make some stories related to that and it will be helpful to u
