GMAT Strategy

Hi, I'm new here, I apologize if this is not the right section for my thread.
So, I need to take the GMAT and pass it with a decent score in order to apply for a business school I'm interested in.
A score around 700 would be more than sufficient for my purpose.
Without previously knowing anything about the GMAT test, two days ago I took the official GMAT prep test 1 twice, getting a 710 in my first try and a 730 in my second try. That came as a bit of a surprise to me, since I'm not a native speaker (and my English is actualy pretty damn basic, around a B2 level I'd say) and I never was that good in maths in high school, above average in my class sure, but not outstanding by any means.
So, what should I make of these two scores? Is the GMAT prep test any accurate? I'm now planning on taking the real test in three weeks, after preparing on the Official Guide. Given my results in the prep test, do you guys think that would be enough to obtain a score of 700 or so?
Thanks in advance.

well...those are the most accurate indicators of the GMAT u can get. its about + or - 20 points of the GMAT prep...

i recognized passages/questions straight up from OG. in fact, one of the reading comp, i didnt even have to read (although i did) because i remembered it from the OG.

i dont imagine that would happen on the real exam. so my score would probably lower then the score GMATPrep estimated for me?
