I have been spending a consistent amount of time studying for the gmat for past 15 days. I have covered Manhattan SC(2003 edition) Manhattan RC(4th edition) Manhattan Number Properties(in progress abt to complete) Manhattan CR(in progress,just started).
I am also doing 10SCs from OG 12 and 3 RC from OG 12 everyday as practice. I have completed Scs from OG 10.
My SC accuracy rate as of now is 80%. Cant seem to get better than this. And for RCs it varies drastically depending on the content and size of the passage.
Planning to cover all the content and practice questions in Manhattan before taking the first test. As my confidence is on the lower side(due to my prev gmat score of 540 in 2007) seeing a low score might push me further down

I am taking the test on May 23rd. I intend to cover OG 12, QUant review, Verbal Review and all 8
manhattan books by april-mid. And then its practice every alternate day till may 23rd along with further questions from Gmat club, Og10 and Og11.
Please suggest if there is anything i am missing out on my plan. Missed to add this: I am not working currently so i am spending about 6-7 hours everyday as of now. Also making flash cards of important points and keeping an
error log.
