spikedsoymilk, I don't think that's too bad. If you take a practice test every four days, you can structure it like this:
Day 1: full length - Day 2: review test, log mistakes - Day 3: do corresponding PS BR passages for your weak areas from that full length - Day 4: do corresponding BS BR Passages of your weak areas from that full length - Repeat or insert break day
That way, you do FL's and passages, and you focus on your weak areas. Sometimes we just have to let go of the idea that "we need to do EVERYTHING". (I struggle with this). Do what you can. Good luck!!
