Your post sounds much more plausible. After some extra consideration, I think I'm going to make study guides for the DAT subjects over the summer (so I can at least freshen my memory). I doubt chemistry will take long to review -- this subject has always clicked for me -- so I will be spending most of the time reviewing biology and calculus, and dabbling in PAT practice.
Then, come winter break, I would have a maximum of four weeks to prepare before taking the exam (should I schedule it at the end of break). This is when I plan to simply take practice tests, nothing else. I will have reviewed the material sufficiently.
I've pinpointed my most effective studying tactic over the past three years -- I work better when I learn the material gradually over time, and then review in a short period -- so I think this will ensure a good performance on the exam.
Here's where I need advice:
I plan to review casually during the fall semester. However, I am currently signed up for 19 credits as well as research and a part-time job. I feel that if I reduce the load to 15 credits (three courses), I will have much more time to study for the DAT. I haven't found many threads on this, but from what I have reviewed, I infer that dental schools do not view this negatively (and if it comes up in an interview, I would just explain it). But I'm still not sure. Thoughts?
