If you love chemistry, there's no way if would dislike the organic part.. In organic chemistry, either you are a champ or a novice, there's nothing like intermediate. And if you understand it well, you'll fall in love with it. And that too in the first sight. Actually, it's kinda addictive. (Though it was my weaker part, I did quite okay in exams). Coming to the point- How to actually prepare to pro level of organic chemistry.
See, the GOLDEN rule for organic chemistry is PRACTICE!! You'll start off with the basic concepts of organic, which is a very important chapter. NEVER learn stuff in organic chemistry, instead understand the mechanisms.. Understanding mechanisms is the most crucial part in organic chemistry.
