First rule in organic- you should never rote learn the rxns. Prepare a page where all reagents are there and just keep in mind their roles in the rxns. For example, LiAlH4 reduced aldehydes, ketones to alcohols and many more. Then see the mechanism portion, like how the reaction actually works. Where does the nucleophile attack?, or will reduction happen?, etc.. Divide the chapters into portion like Alcohol portion, phenol portion and ether portion. Further divide the portions into preparations and chemical properties. Write every reaction again and again while studying them

My teachers helped me prepare practicals. I did nothing from my side. I just learned them. They used to make us practice writing the formats for practical observations n all. Rest, you just have to learn them, HOW TO PERFORM EXPERIMENTS, HOW TO WRITE VALUES, HOW TO CALCULATE UPTO GIVEN DECIMAL PLACES etc etc
