2nd attempt: 1st- 570, need +600 & have 3 weeks to study

Rhyme! Thanks for responding I was going to direct these questions to you personally, but u seemed pretty bombarded.

Well, when I studied for my first attempt in March, I first joined a kaplan course, at which point I realized that I was pretty bad in everything. I learned some strategy (like with DS, always start with 2nd option etc.) THen I took up with some private tutoring, which didn't really help me either-- it was just homework assignments, with no real strategy at all. As I did the hw, i did not time myself. and the few times that I did, each problem always lasted more than 2 minutes for me. I think some of it is that i might underestimate what i know, or that i think too much about whether or not i'm being tricked, what difficulty it is etc.
On to verbal-- RC wipes me out; i get so impatient. SC I"m ok in but I get pretty bogged down in the answer choices.

Tests:
I took like 8 practice tests. I took one with the essays. My first diagnostic was like a 400 (yeah, i know), and then i gradually made it up to the 500's. THe highest scores I hit were 610, 620 then 640 (1 week before exam-- they were all kaplan) , then 3 days before the exam i made a 580 (old gmat prep), and then one day before the exam i made a 570 (newer gamt prep). So, its improvement, but by the end, I was so tired. Tired of studying. I had very little sleep and was really stressed out and kept reviewing my notes. I tried to keep error logs after i took exams, but i was missing so many, that it took so much time. Can you point me to your error log system, bcuz i am unable to find it in the forum.

Test Day:
I know that I totally looked over RC and the impact the essay portion would have on me. Also, I just have this mental block-- I'm not incredibly obtuse, these tests just do a number on me.


IN general: NOw, its been 3 months since the exam, and I feel like i'm almost at square 1. I know now that I should practice with the essay and not blow off RC. I think it was a mental block for me-- i was irritated that on an already hard test, RC passages just made it uneccesarily harder! ahem, anyways timing is a huge issue for me, though I did not concentrate on it enough bcuz I felt I wasn't strong enough in the content. Also, I really don't know how to create a specific study plan for myself at this point-- i'm a little gun shy!

question-- instead of buying the manhattan books, can i subscribe to manhattan material online (in the interest of time)? which ones specifically?

Thank you so much for the help, rhyme!!!!!!! looking forward to hearing from you.
