Hi everybody!!
I have a psicologist friend and she told me that if you ask you to do a Raven test, that is a very good sign.
If you had not like them, for what would they ask for more tests?. My friend explained me that they will probably check everything.
Raven test normally are used to measure the logic, they are logical reasonings.
Dont worry, if they have asked just a few.
Regards and good luck!
