I did two to three blocks of UWorld questions a day and read through all the explanations. This took me three to four hours.
I also did one section of First Aid e.g. all of cardiology, all of reproductive etc, sometimes two if they were shorter sections, this probably took me another three hours.
Did corresponding chapter of Goljan path or BRS path, depending on which topic it was ( I used Goljan for some topics and BRS for others), probably took me two hours.
What arielred said is a great way to approach studying for the boards. The most important thing is having your primary books and USMLE World. I recommend First Aid and Goljan as your primary books. If you know first aid and Goljan through and though you can guarantee yourself a very solid score. There is no substitute for USMLE World; it prepares you well. So people say Kaplan is better because the questions are harder. However, USMLE World's questions are so much like Step 1 it is ridiculous.
Give yourself enough time to see all the big sections at least twice. Make sure you study pharm everyday.
