GMAT: one month to go, need some advice

Hi,
Both of us seem to be sailing in the same boat. I have my Gmat on the 10th of June

My scores are more or less the same as yours, with maths being on the higher side and English stagnant in the 35-40 range.
Improving English is really difficult especially if you have got just a month in hand. But I believe that attacking RC is easier than attacking SC .
I typically give 4 minutes for reading an RC. I begin by reading the first paragraph slowly and taking down notes so that I understand it fully and then improve my speed in the subsequent paragraphs. I try taking down notes after each paragraphs. By notes I mean simple 5-10 important keywords and some sketches to map the para into my brain.
I give roughly 45 seconds for each question.
It has improved my accuracy from 70 percent in RC to 95 percent. Hope it helps you too.

Hey I have a question for you. Dont you think that the QC and DS sections in Kaplan Practice Tests and PR are way too easy ?? I am consistently able to solve all the questions with some 20 minutes to spare ??
How do you practice for difficult problems in Maths ? There seems to be a dearth of tough material when practicing for Maths !
