My first recommendation is to do the full analysis in the article that I linked to last time and to tell us the results of that analysis here. It's useful to know that your quant and verbal both dropped on the real test, but that's not anywhere near enough data to know where to go from here. You need to help us to help you here. :)
For example, here's one reason why your score may have dropped:
I took the Manhattan gmat practice test the day before my exam
Taking a practice test the day before your real test is a bad idea. That just tires you out.
I definitely have a timing issue
Please elaborate. What is your timing issue? Where are you spending too much or too little time? What happens as you start to get towards the end of a section - are you way behind or way ahead? If way behind, what happens? Do you speed up? Start making random guesses? Just run out of time before you finish the questions? What happened on the real test relative to your timing?
Give as much detail as possible.You can also use this article to help you figure out the detailed data on your strengths and weaknesses:
http://www.manhattangmat.com/articles/e ... -part1.cfmAnd share that analysis with us (note: don't just post the data from the score reports; actually analyze the data according to what the article says, then share your analysis here).
Secondly, I have noticed that in the MGMAT exam i have many wrong answers but still got a score of 580?
Yes, that's how this kind of test works. Log into your student center and read your copy of the e-book The GMAT Uncovered. Pay particular attention to the section on scoring; this will explain to you how the test works - and this is important information to know before you take the test again. If you have any questions about the scoring after you have read this, please come back here and let us know.
