I really found this thread helpful when I was studying for my GRE, and now that I have completed it I thought I would share my experiences in case anyone else might use it for their preparation. I am a non-native English speaker, as well as a physics/engineering major. So mainly I thought the maths part would be easy enough but I dreaded the verbal. Initially I studied a mix of the ETS Official Guide and Manhattan's 5lb book, shifting between the maths and verbal sections. Just while studying those two books I took the following practice exams; Q V ETS Paper test #1 162 156 ETS Paper test #2 164 163 Kaplan Free test 164 152 Princeton Test 6 161 156 Manhattan Free test 159 158 Manhattan Test #2 159 158 ETS PP Test #1 164 157 After this I realised I needed to do something to boost my verbal score, as I was hoping to get at least 160. So I went ahead and bought the Magoosh premium, and I hate to sound like I am advertising for them, but that really made a world of difference to me. The video explanations were extremely helpful, in particular on the verbal sections I could develop a few strategies and generally felt a little more confident. So I did some more practice tests. Manhattan Test #3 161 162 Manhattan Test #4 161 162 Magoosh PT #1 165 159 Manhattan Test#5 164 156 Three days before my test I downloaded the Magoosh flashcard app and do what you are probably not supposed to do; I spent two whole days just before my test memorizing 1000 words. As in relentlessly going over them until I knew the exact definition of them all. And then I did another powerprep test; ETS PP Test #2 163 166 I was a little surprised by this, and thought it was great but probably not particularly representative of my verbal score, seeing as I had never scored this high. Anyway, I studied some more flash cards and going into the test I had Q163/V160 as my minimum targets. Actual GRE 164 168 I was hoping to get a slightly higher maths score, but to be honest I think I was a little arrogant in thinking I was an engineering major and the maths should be easy, so even when studying I kept doing the same thing and didn't really bother to identify what I was doing wrong. On the other hand I was so worried about my verbal score that I scrutinized every question until I understood what the GRE is actually trying to test. Studying those 1000 flashcards over two days is probably the best thing I did. A surprising number of the words came up in the test and I had no serious doubts about my answers. As for the different systems, the Manhattan online tests were only good for testing maths, as it was harder than the actual GRE, but still had similar questions. The verbal has nothing to do with what you will meet on test day, and they use low-frequency words which would be pointless to try to learn. As I said, I thought Magoosh was really good and if I did it again I would buy the package and download the flashcards from the very start. The actual test was not as difficult as I thought, although I did get three maths sections so it is hard for me to tell which ones I was being tested on.
