What's a student's daily workload/schedule like for maintaining 3.5+? How about 3.9+?

<p>Here’s a thread I found about premed @ Caltech <a href=“http://talk.collegeconfidential.com/california-institute-technology/497482-looking-more-info-pre-med-please.html?highlight=premed[/url]”>http://talk.collegeconfidential.com/california-institute-technology/497482-looking-more-info-pre-med-please.html?highlight=premed&lt;/a&gt;&lt;/p&gt;

<p>Can any of you recommend any beginner resources/guides to writing math proofs? I can link one idea to another, but I have no clue as to what to state in the beginning and what to write between ideas.</p>
