Hello all,
Bonvivz: Yes i was working during the gmat preparation, except for the last 3 days. I did my best to squeeze in two hours everyday (more than that I felt I was not as efficient), focusing either on quantitative or verbal but not both on the same day, and worked the same during weekend (I have a job where sundays are just the same as any other day, so no extra gmat hours on week end). If you have week ends off, I would suggest doing 1 test on either of the days.
What you decide to do during these two hours will depend on your weaknesses. For me it was quantitative because although I am an engineer I was very disturbed by the data sufficiency questions.
My thoughts about the different sections:
Verbal: I found that critical reasoning does not need a lot of practice once you have understood the "trick" to formulate the answer before reading the question choices. For SC, practice really helped me recognize the patterns of gmat errors. I am a foreigner but due to m y limited time, I chose to focus on strategy instead of grammar rule for this part. As for RC, i had enough time on my hands to read calmly. I always took notes because it helped me remember the passage better, but almost never referred to my notes.
Quantitative: For problem solving, I spend about 3 days reviewed math basics and then did practice exercises to improve my calculus skills: faster, less mistakes. DS was another story, I am pretty sure it is the reason of my not so high quant percentile...
GMAT club tests really helped for these, the answers are very helpful (as opposed to the OG which details all the maths....exactly what you want to avoid doing...)
I am not going to post a detail of how many exercises I did each day, or
error log, because I am trying to make a point that you can do it if you work smartly, which means finding the material that is best for your, and using the famous 80/20 strategy...I did spend about 3 hours at borders going through most of the study books before i bought the one that seemed best for me. I hope this is helpful to you, and good luck!
