Hi Kourosh,
I just took the same exam, and got a 73%. That mock exam was the closest one to the real exam, that I have done to date. There were more lengthy code style question in the real exam when I did it, and you are right, it
is really quite hard on the eyes. I think that the real exam is a little harder than Marcus' exam, but with 76%, you are probably looking at passing, but just!!
I'd say polish on the areas that you got wrong, and go for the real exam. Good luck!!
