how to study organic effectively?

You pls follow MORRISON and BOY’D its a very good book...
and then go for practice exercise.

1. The primary source for theory is your class notes. Second comes NCERT.Take notes properly, try to note down each and very word your instructor says, exercise questions too. Revise them regularly.

2. General Organic Chemistry (GOC) is most important. It's concepts will help you in predicting reactions. It has some amount of logic attached to it too.

3. While studying reactions and their mechanisms, try to understand each and every step, because JEE generally twists one of the intermediate steps to trump you.

4. For problems, solve your package and an additional workbook. Ask your instructor for recommendations.

5. So and ideal approach would be, to study the notes, each reaction and each mechanism. When you feel satisfied, start solving. Package first, workbook later.

6. While solving, you wont be able to solve each and every question. Also, all the questions you solved, won't be correct. So mark such questions and attempt them again later during revision.
