<p>1) Different sections can either meet at different times, or have different TA’s. In phys1a and chem1a, there is a “supersection” that goes into a little more depth- you miss out on <em>nothing</em> by not being in it (before I came here, I thought I just had to be in the supersection, got here, and realized it didn’t matter)</p>
<p>2) You can get p/f units for band and orchestra. If you can play your instrument, you can be in concert band- there is basically no chance Bill (Bing) won’t let you play. Orchestra obviously doesn’t have quite the flexibility for winds- you actually have to audition and do well to be able to play in orchestra.</p>
