Hey, I studied for the DAT during my school year and I did well. I think the main issue is time management. As long as you recognize the amount of time you need to spend on everything, you should be fine. If I were you, I would schedule your DAT for that spring semester, and you can always push it back. I found that once I set a date, it became easier to get motivated. As far as study plans, I would study for everything simultaneously otherwise you might forget some material. What you could do, is buy Kaplan Blue Books and just look over it on winter break and understand the PAT rules and format of the test, so that when you start to study, you are 100% studying/reviewing. I think that studying while taking classes was kind of helpful because it put me in the mindset of studying rather than wasting time you could spend relaxing. Worst case scenario is you have to push it back (which I think you can do for free as long as you do it early enough.) What you can also do is start to look at some study plans and breakdowns and formulate an idea of how you will tackle it. What I usually did was get my class work done in between classes if I had time off and maybe before dinner, and then used the evening for DAT. I would suggest just reading Schaum's/Cliff's at night for an hour or so before bed (you could probably start reading that now if you want since repetition is key for Biology.) Also, as far as RC, I really didn't do anything, but maybe just start reading the news. RC is really dependent on how comfortable you are with reading and comprehension. Hopefully this helps, feel free to PM if you want more ideas.
