<p>The thing about the 3 series is that it’s not a major prereq for Biology. You can take it as late as your last year if you want so by then you should already know what is entailed in being a bio major. If by some miracle you don’t know anything about biologists… there’s even a class you could take called careers in bio or something. You should switch before ever taking physics, if you do.</p>
<p>That said, I’m not disagreeing, the 7 series is enticing for those above reasons.</p>
<p>Yeah, I was one of the fools who took the physics 3 series. So regretting it… but I’m so happy I didn’t take the garbage biostats class and instead took math 2D and 2J. looking into grad programs in computational finance and chemistry, maybe after staying for year 5…</p>
<p>here’s why you don’t want to take the “easy” classes:</p>
<p>you’ll be competing with the premeds, so it’s not actually easier than the 7 series.</p>
<p>the problems are not significantly easier. try doing electromagnetics with middle school math.</p>
<p>but the reason you want to take it early (2nd year, I suggest math first, as math gets you into more stuff) and in the 7 series is because if you don’t, it’ll be extremely hard to switch to engineering if you want to. but if you take it 2nd year you still have time to switch to chemistry with no problems, just remember to tell the department so you can get signed up for chem 5, the chem majors only programming class. if you still like bio there’s a biochem emphasis that’s ACS accredited.</p>
<p>remember this, chem/BME students can do biotech or even go to medical school, bio can’t do drug synthesis or design MRIs.</p>
