If you do all the back exercise and intext question of chapter for organic chemistry than it will be sufficient to score good,you also learn name reaction which is asked in Exam.
My personel suggestion is that Try to follow 3R technique for organic chemistry.3R Technique is READ,REVISE,RECALL
Hope this helps you
