I'm studying 5ish hours / day. I just started 10 or so days ago, and I've just got 10 or so days left. I've finished all but two of the EK lessons, which I'll finish by the end of today (hopefully, but I'm just not getting this optics stuff). The next 10 days'll be full of practice problems and re-reading EK Bio and EK Organistry.
I started out with a 38 on AAMC CBT3 (before studying), and it's been downhill from there..
36 on CBT 4... 35 on CBT 5.
I might be burning out, who knows. I'll take CBT 6 tomorrow. Hopefully now that I'm a lot more comfortable with organistry and organismal biology I'll do better.
On CBT3 I scored a 14 Bio-wise, and on CBT4 I scored a 9

. On CBT5 I cleared an 11.
