You're kind of doing what I'm doing. I took the famous 8 week plan and expanded the first 4 weeks into 8. Basically I light read a chapter of Cliff's AP Bio/KBB one day, do Chad's videos the next. Then on Day 3 I reread the 2 chapters I read on the first day, but this time I read them more in depth and I make an outline on the computer (I think this is key, especially since I'll be taking my exam in May and will most likely forget a few points) of the information. Day 4 is more Chad's videos.
While this is good, it's probably going to take me around 9-10 weeks to get that done, because exams force me to take breaks the day before/ I can't study for 8 weeks straight nonstop. So I'd suggest doing something similar. Read one day, do something else, outline/in-depth the next. It really helps keep all the information in.
After I finish this reading/videos (probably by mid-late March), it's going to be straight Destroyer and practice exams until the DAT. Hopefully I can go through Destroyer at least 3 times and take at least 6 practice exams before the big day!
