Recomendations On Planning Weekly Practice Tests

I am looking to take a practice test a week like Eric did under simulated situations. I have not yet taken any but would like to plan them out in order. I was thinking of just doing them in the same order that Eric took them but I read on the sticky that people really like Manhattan's practice tests. Should i just focus on these at first? So far here is my list (copy of Eric's) Any recommendations would be greatly appreciated.

Thanks guys!

Excuse the dates
