CVEN2301 - Mechanics of Solids (Civil Engineering)
Ease: 7/10 - Fairly easy as long as you kept up with the content. Make sure you do enough prep for the quizzes.
Content: 7/10 - Not the hardest content, but there are questions which are, at times, confusing. Shit starts to get a bit more...
CVEN2501 - Principles of Water Engineering
Ease: 6/10 - Not very easy at all. Lots of calculations and problem solving required! I would suggest you keep up with the content and attend lectures (unlike me).
Content: 6/10 - A fairly decent amount of content, make sure you revise regularly...
Whetherill does have bad pass rates. If you are not familiar with the roads there, I'd suggest you take the test somewhere else or try booking the test when its quiet on the road I.e. earliest slot on Sat, Sun or around 11 on weekdays (in my experience in driving around that area)
