SAIT Entrance Exams ( Mechanics )

On the 15th i will be taking an Entrance Exam at SAIT for a Heavy Equipment Technician. Has anyone else taken an exam similair to this? Maybe just for a straght mechanic or someone in the same kind of field? Just kinda curious if its really hard or not. I really don't think i am any kind of expert in the mechanic field right now as i havent had the right kind of tools to work on my car. Although i am very interested with working on cars and such.
So if anyone has taken the exam could you just give me a breif overview of how hard it is, what kind of questions they ask, etc...

Thanks
