SC - my arch nemesis.

Good afternoon everyone!

I have been a long time lurker on this forum and am writing you all in an effort to obtain help on my GMAT journey.
So far my Quant, RC and CR prep seem to be doing alright together with some improvements on CAT's from my initial GMAT prep exam. However, my approach to SC seems to be garnering much too inconsistent results for me to reach the heights of 700+.

I did the E-GMAT verbal course and found it good in explaining all the concepts covered. However, now I seem to find myself quite lost among my 30 pages of hand written notes. I don’t have a solid step by step strategy when I solve SC’s. I scan the answer choices for any easy to spot differences. Then I tackle the original question to look for anything that seems out of place. Most of the time, I get lost in jumbled long sentences and feel like I am searching for a needle in a haystack. Only that I am armed with a guidebook as fat as a bible with 1000 tips on how to scan the way depending on the color of the hay, the placement of the hay, the type of hay and what not.

I find myself too often going for the answer that ‘sounds about right’. This may be due to the fact that English is not my native language and the fact that I learned English mostly by reading, watching movies and listening to music. I never learned grammar. Nor do I know much about the grammar rules in Swedish either.

I am thinking of ‘drawing’ a temple of some sort in the shape of:
1. Scan for SV error
a. Especially look for x..y..z
2. Scan for pronoun errors
a. Tips..
3. Scan for parallelism error (“and” “or” in there?)

However, I feel quite lost.

Dear grand masters and keepers of this oasis of knowledge called gmatclub, please bestow upon me your wealth of wisdom!
