Self-study physics or chemistry - possible?

<p>I have a question for those who have used PR’s physics book. Did you find the review questions at the end of each chapter representative of the real test questions? I haven’t found them too challenging, but they are taking me a long time to complete. I usually spend 60-90 seconds per question, well above the 45 seconds or so each question should take on average. Can I expect the questions on the real test to be quicker to solve, or do I need to work on my speed a lot? </p>

<p>Once I get the formulas and everything set up it goes pretty fast, but it takes me a little while to think through all the information the question gives and decide exactly how to solve it. I’m thinking that may just come with a lot of practice, so if I do need to speed things up, are there any other sources with good practice problems you would recommend?</p>
