Hi, welcome to the club!
I understand that you have already hit the 700 bar on the GMAT, congratulations.
Look, verbal score of 41 and math score of 41 could be compared. Just look at the percetiles : V41 is 92% and Q50 - is 93%. Only 1% of test takers receive 46 and abive on verbal, whereas for Q 51 is equivalent score.
See my thread below.
As for 1 week left, it depends on how much time do you have, I would recommend you GMATCLUB Math Tests.
http://gmatclub.com/tests/. This is considered the best practice for the Quantative part. People claimed that after this practice they scored 48+. See here results of testakers and correlation to Q score of the GMAT
result-correlation-between-gmat-and-gmat-club-s-tests-30989.html I would recommmend you to analyze your mistakes and to note why you gone wrong. Is it lack of concept or a careless mistake.
Q49 after 8 wrong at the end? this is fantastic! I think you score would have been 50 or even 51, had not you missed last questions.
