sbharath,
I felt the same when I started. I was really frustrated because I expected that I would be more familiar with the material that I was about to read. But I was not. So I began to doubt myself. However, I have recently finished all the 8 guides and the accompanying problems from the
OG and the 2 reviews. It took me around 2 months with my normal studying pace. Then, I decided it is time to read them all again with the extra focus on my weak areas.
Here is the good part. I get to read one guide/day without feeling I am rushing (I decided not to go over
OG problems from the
error log just yet). I can finally feel the limited scope of the test, especially in the Quant section. As far as the verbal section is concerned that could be tricky because in my opinition to do well in Verbal if you are a non-native speaker you need to read outside of GMAT material.
GMAT Fiction is one example of outside reading.
So if you ask me, the beginning is by far the hardest part of the GMAT. I also think that once you are done with the first round of reading the guides, things should become significantly easier.
To try to answer your questions now:
1) Make sure you do the referenced problems from the
OG once the guide tells you so. It is a good way of learning. Also, make sure you have an
error log when doing problems from the
OG/Reviews because it will help you identify your weak areas.
2) Perhaps the best thing you can do is this: Schedule the test right now at the latest possible date in May. Then, you will know exactly what amount of time you have left. Allot the time on the basis of the size of the material and stick to it. That would probably mean that you will have to rush but it all depends on your studying pace. Sorry I cannot help you more.
3) I find
MGMAT amazing. The only thing they lack, or maybe could not help people out with, is the RC part of the Verbal. As I said, I believe that is where
GMAT Fiction kicks in, or how much you read at work (i.e. you are an analyst) and/or during your free time.
Keep your head high and it will get easier with time!
