<p>Yes, yes, yes. Also, get help early. This doesn’t just mean academic help, it means emotional/mental help, if you are starting to have trouble. Don’t wait until you’re in crisis mode. If your emotional problems are connected in any way to your academic problems, the counseling deans in Student Support Services can help you with <em>all</em> of them.</p>

<p>No. Mollie explained it well. Like she said, it’s not a reflection on your ability.</p>

<p>No. MIT had a contract with the people who did it, to let them put it on for some number of years. When the contract ran out, MIT did not renew. So, no more Playfair.</p>
<p>Another piece of advice: Some professors who are terrible lecturers are much better at explaining things one on one. This is another reason to go to office hours. On the other hand, remember that there <em>are</em> some professors who are just jerks, or terrible teachers in general (though they are not necessarily the same people). You can find people other than the professor to teach you the material if need be - your TA, a tutor, upperclassmen on your hall who are majors in the department, etc.</p>
