hello again,
I can say that I got my answers by my future employer. they've sent me some links where I can download some practice tests and information about.
I tried the tests for once and I did start to find out what my strong and weak parts are. all in all, the test itself needs basic knowledge of all elements; physics, maths and english (no MIC for us). all I can say is physics is not what I've expected. it asks much more physic knowledge than some regular training; like you have to know and be able to analyze a closed circuit, basic knowledge of AC/DC and have had a basic physics training at least in your high school times.
about maths; it seems you really need to derive a system suitable for your style. otherwise it becomes harder and harder when it gets faster by level-ups. conservative solving methods become useless through levels. I'm not sure but in maths section (not mental arithmetic) the tutorial says that we can use pen and paper but no calculator not along with some info about we won't be able to use in real test unlike the other tutorials which it indicates that we will not be able to use any pen, paper etc.
and about the mental arithmetic part; it basicly needs some memorizing techniques which you need to know at least the squares and square roots of numbers like -lets say- from 2 to 25 and vice versa. also being able to factorize is essential.
the hardest part I've found for myself is the part that the lady reads some numbers with random order and random *_amount_* . this part makes it difficult because it may end up at 5th number or 25th. this is why it is called running memory span. at last but not least, the test asks you to write the digits in reverse order *ugh*.
cube rotation, concentration, spatial orientation, visual memory parts are totally about talent. person could study these just to know what it will look like in real test. some techniques might be taken into consideration about all these but the basic is person has to be able to think in 3D space.
pretty long post but if there are people like me wondering what this test looks like, they could get a clue.
thanks and good luck.
