I keep telling myself that the exams can't be that difficult since everyone else has passed them.
I wouldn't say that everyone
else has passed them. I know more than one person who has tried two or three times before giving up. Some people just have a difficult time getting their heads around the math - that's where a tutor, or even just a friend to study with, can be invaluable. Sometimes all you need is a nudge in the right direction and everything becomes wonderfully, sparklingly clear!
Martin is right about the difficulties of studying while trying to work, maintain a family and..., you know..., have a life. I was fortunate inasmuch as I did my studying Way Back When U.I.C. (as it was called then) would pay benefits while you went to school. If you're trying it on your own, you definitely have to get out of the house with its constant distractions. I found the local library to be an excellent place to study which also had ready access to other materials than those which you've lugged in. If your significant other balks at the idea, you might try leaving a few Positions Vacant listings which mention the better salaries available to those with higher tickets lying around - I understand that BC Ferries pay their engineers really well!!
If it was easy, everybody would be doing it....
