Hello,
My background first: mechanical engineer from Germany, really not into CAT or standardized tests (I cannot remember a standardized test to have written in the past. neither on highschool, nor at the university. So it is a really hard test for me).
I'm reading this forum since November 2011. I took a practice exam and scored 400 with one week preparation. I did a lot of mistakes on DS problems and verbal section.
Then I took a break over x-mas and my desired university accepted me for September 2012 intake. But I need to take the real GMAT so I've bought the 8 books from MGMAT and, what can I say? Best books I have encountered so far. Even better than the OG12 (except the questions in OG12). You did a great job with these, easy to understand, books.
I have now exactly 4 Weeks for preparation (working full-time :( ). Target score 550-600. Finished Number Properties Book today.
My strengths: problem solving and geometry.
My weakness: Data Sufficiency in general (need more training on rephrasing questions), Word Problems AND, as a non-native speaker, the verbal section. Sentence Correction is okay, not that difficult, 60% accuracy. Its just practicing and according to my english, which I use very often because I am mostly abroad on business trips, it is not that hard to recognize verb-tense, parallelism and idioms issues. I will focus on this on my last week. But I am really struggling with CR. To inform you: I didn't take a look on the CR book yet. But everytime I try to solve a CR question, it'll be wrong. So I am thinking not to take too much time on it.
Any suggestions?
And my second question, which is very important to me: every book has an advanced tactics section. Is is mandatory to learn this tactics to score at least "550-600"?
Kind regards from a MGMAT fan
edit: I am learning at least 4h/day at the evening. So I am willing to learn as much as I need.
