Can u please tell me how can I solve questions on organic chemistry and learn reactions

When reading a reaction first time try to read its mechanism and understand it like when you are studying Ozonolysis first learn about its mechanism and how it proceeds . Then you can learn shortcuts for solving the questions fastly. Learn and understand the basic rules very clearly like Morkonikov Rule , Saytzeff Rule because if you don't know these terms then you can do nothing in reaction mechanism .

Try to solve more and more questions because in organic chemistry there are lot of exceptions , when you think your answer is correct in many cases it won't .
