I took the GSE2 test 4 times, each time the % went down, finally on my 4th try at fucking 2% i made it, 7 out of 250 people, i was the 7th.
I'm a horrible test taker so it took me 6 (maybe 7, I can't remember) times to make E5. The 2nd through 4th tests I studied for and noticed my scores never improved. Then I took the advice of a Chief that used to design the tests. He told me don't study, just study the question and answers. This is basically what he told me on how to take it.
Always keep count of how many A, B,C,D answers you mark. Skip the ones you have no idea on. At the end of the test go back through to the ones you skipped and mark them accordingly. There are always 50 of each answer. The others, if it's a true or false answer, 9 times out of ten the answer is true. The longest answer is also usually the correct one. And know your BMR.
I took that advice, my 5th test I missed it by 1.11 and the 6th test I made it by 22. All my other tests, I missed it by 10 or more even with EP eval.
