<p>Does anybody know any good ways to improve in Math and CR? I'm struggling on both subjects and I'm looking for some good advice. Thanks</p>
<p>Grubers for math, CR read a lot.</p>
<p>I really like PR's strategies for CR.</p>
<p>For math, you really need to just practice as much as you can.</p>
<p>What practicing methods would you recommend?</p>
