<p>I have to more midterms to take, and I must do well on those. I find exercise problems in my textbook (Sorrell's organic chemistry) much easier than actual exam questions. What books give you quite challenging organic chemistry problems?</p>
<p>Try Vollhardt's Organic Chemistry, that's what we use here in Berkeley.</p>
<p>We have a choice of Vollhardt's or Bruice. If you want supplementary material, id recommend Organic Chemistry as a Second Language by Klein, and Pushing Electrons by Weeks. Not sure how much of a challenge they will be compared to your exams, but our professors has these as optional supplements to the textbook.</p>
