I read the driving permit booklet probably 10 times cover to cover, before I ended up taking the actual test.
Wow! that is some real dedication you have! Did you manage to pass the test? 
I did! I did tremendously, got them all right. I think I went a little overkill, to be honest..
Wow that is great! I am so proud of you. And hey, it never hurts to study more. :)
