<p>I know this may have been discusses already but I'm still confused. I got a 3 on my AP Calc AB test and a 5 on my IB test. I really has to struggle in HS in Calc. I'm kinda torn between Neurobiology and Business at this point. I was wondering, should I subject myself to 1A? I've heard stories about how hard 1A really is. Can anyone tell me the difference between the two classes and the difference in the level of difficulty?? THanks</p>
<p>which IB test? it's nice to find a fellow IB-er! </p>
<p>~Oh, and I suggest 16A, but 1A for Neuro... big diff. between majors there</p>
