thx, would be glad to hear some more ideas !
BTW: why are some questions labeled as "hard" on the Archer, but are labeled as a "600" around here (same thing for the opposites)?
Not sure - I found as my studies went on that really the difficulty of a question was dependent on my own strengths and weaknesses.
If you are looking for a general rule on relative difficulty --> I believe the common wisdom on this is that the higher the Question #, the more difficult in the OG books (Difficulty #1 < #100).
Additional note on the MG Archer --> I found it useful for learning to categorize questions quickly by Content Area / Subject (example: John drives x mph and started 2 minutes ahead of Bob..... --> quickly pick up on the patterns of questions to know Word Problem / R*T=D --> now use x or y strategy depending on exact question).
MG Archer has all of the data there, so you can quickly see what the question is and in the explanation it goes over in detail background on the concepts tested to make sure you identified all of the relevant topics being tested in the question.
