How many questions is the test

Im sorry i dont remember. But you do the test on your home computer ir device at yer own pace. Its not hard really. somehow I actually miss that part of the test because my device was acting stupid and I still passed with flying colors no less but when I read it again with my roommate and helped him do his oh my God I remember this part so it really wasn't that hard at all I just don't remember how many questions there is like picture questions where you have to put the correct picture on the right column with the proper explanations and it's really simple but you do everything at home and then you just go down there taking grab your stuff and go didn't take long at all

I had 20 questions my first time ever taking the test
