You can't learn the tests, if you can't do it without outside assistance maybe the job is not for you.
too bad I passed all the tests without too much difficulty but didn't get judged positively at the interview after having answered well even to the math/physic questions (maybe someone did the call..nevermind)..I really wanted to do this job and I felt suited for it..I guess I'm gonna try elsewhere..anyways, good luck to all those who are gonna go get tested soonly..
