July, 5 - DS day

Most of the day spent dealing with Data Sufficiency questions at testmagic. In the evening made couple of sections from DS1000 - few mistakes, all of them in the strangely formulated questions (like a story about a jeweler, who sells an item at some price; first option gives data that he made a discount and second option gives only selling price. Do I have to suppose always that there could be discount involved? It is never known either yes or no, maybe there even was involved something additional, I can invent many things to change the original price from real-life cases. Not sure that have to take a suppose of this data).

July, 5

Sat me down to the laptop yesterday, throwing away all the boring things about going to a lake to have a swim after the exhausting heat during the day-time (+34 for me is quite much :) I have more of a Polar-man), and took the full GMAT Adaptive 4 from Princeton. Results are neither bad nor good. Nor good because I've got only 637 (Q43; V34). Neither bad because my friend, who scored 700 had 640 at the real test a month before the exam. So, I can gain the missing during the month of preparation. Besides, many of the questions on this test were of different patterns that I met before, giving me new material to work with. Nice, but have met several problems that did previously wrong, but to the current moment have already explored method of their solving.
Late evening was spent to reading and drilling Data Sufficiency in Princeton - DS was the only type of the problems I got wrong in Quantitative section.
Before the test, figured out that the wheel on the car was cut, suppose when touched the tram rails, so, had to go to tire repair, but had several scientific articles to read, so the time was not wasted.
In the morning slept too much - up to 8.15...

July, 4 - Independence Day

Hooray!

The day started great, woke me up at 7.30, that is already one hour earlier than usualy, and it gave me an hour to sit with 60 SC questions from GMATTER. Result - 32% errors. Have doubt about some questions with verb tense and with some pairs of words. Going to check these questions with testmagic reviews.

My challenge

Currently I have placed an aim to reach 750 (Q50; V42), that does not seem to be too unreachable. Need only to improve some maths (that means to make no mistakes at the beginning) and improve RC together with SC.

Started

The decision day has come, I need to stimulate myself to get up early, become an early-riser, go to bed also early :) and spend the morning time studying for GMAT.
What are my current results?
Took Quantitative section in Powerprep recently, scored 47.
In Kaplan diagnostic, got to 650 total
In Princeton, a week before Kaplan - 640 total, gaining something like 48Q, 38V.

Having analyzed both results, can say my favourite: "Man, there is still room for improvement".
Current success in the areas are (from weakest to strongest):
avg.err.RC - 38%
avg.err.SC - 34%
avg.err.CR - 27%
avg.err.PS - 15%
avg.err.DS - 13%

avg.err.Overall.Math 14%
avg.err.Overall.Verbal 30%

Verbal has much to do with it.
First of all, have to improve my Reading Comprehension. After having read various sources, found a way for it:
1. do not subvocalize while reading and due to it increase the speed of reading.
Funny, but used the special on-line read speed checker that showed the result 328 wpm and more than 90% comprehension.

I'm stuck in reading more with scientifical passages, especially biology. There are nice resources for improving it - Scientific American :) it has so many nice things about biology to read about.

Another weak are - Sentence Correction seems to be improving after certain number of questions.
