Will be tough and close. Depends on how much effort you invest and what books you use (see bottom of my post for suggestions).
GMAT Prep is close to the GMAT but can be a swing of up to 40 points if you are negatively impacted by stress or you could actually do better if it takes stress to get the best out of you.

* Get a good GMAT Book
* Make sure you review your mistakes very carefully and print them all out and keep a folder that you can review once a week to make sure you dont' make the same errors again. Would spend at least 2 hours per day and 4 hours on weekends taking full tests.
* Split your studies into math/verbal - don't do both at the same time
* Give your best time (not bus ride or lunch break) but morning and make sure you are not interrupted
* Take full tests on weekends - the AWA too to simulate the real test experience. Review your mistakes and invest at least an hour into questions you did not know, guessed, or got wrong

Thanks for your reply.

Actually I am off work for the past 2 months and have been studying the whole day pretty much every day. I am doing exactly the same thing as you have suggested.

Re-viewing my mistakes after the tests and spending sufficient time to understand them so that I dont repeat such mistakes.

Have split my work into Verbal and Quant.

Took a test yesterday again and got a 430 (q28 v22), I did not answer the last 6 questions in quant and was distracted at times with my Husband asking me things inbetween. On the verbal, I could have got a hell lot of questions right, I narrowed down to the 2 most probable choices and chose the wrong one (in most cases I chose the wrong one after first marking the right one). I am pretty confident I can up my verbal score to a 40 because what I can see is I know the approach and the method and when it boils down to choosing the right answer between 2 final choices, I chose the wrong one (they both seem very fitting to be the answer), SC is good at the moment and I am scoring around the 70% range.

CR is also fine with around 60% accuracy and with a little more practice I can go up to 70%. (I TEND TO CHOOSE THE WRONG ANSWER BETWEEN TWO ON CR MOSTLY).

The only area which I need to improve in verbal is the RC where my scoring rate is only about 55%. I shall learn the approaches well and give time to practice so that I can improve.

On the QUANT section, I really need to improve my timing, my scoring rate now is around 60% and I do not complete the section in time, so with practice may be I can up it to about 75%.

I've got 3 weeks to go and would like to know what if I can reach my target score of 600+ with practice, I am willing to work very hard and do any kind of practice to achieve my goal.

Please advice

Regards

Sam

I would suggest you to write the test again , but make sure you are alone with the Gmatprep and there is no one to disturb you.


I always follow this for timeing and it always helps:

Questions--Start---Stop 
1-10--------1:15---0:55 
11-20------0:55----0:35 
21-30------0:35----0:15 
31-37/41--0:15----0:00 

make sure you follow this timing chert when you sit for the test this time. The chart looks pretty simple but require a little amount of practice.

Please check the Gmatprep score this time , if with no disturbance and good timing strategy you still have less than expected scores (70% and below) , I would suggest you to stop taking the tests for some time , review the wrong answers , study the basics again for them and then take the test again.

Hi Sam one thing you must realise is that you absolutely MUST finish the test. Under no situation should you leave a few questions unanswered. If you leave 5-6 questions unanswered the penalty that gmat throws at you is very severe. You can easily lose 100 points if you dont finish the actual test (did this happen in the real thing ?). If a question gets too hard, guess and move on. But definitely finish the test. Good luck.
