I got to agree with dc302 here, don't waste time doing ESD1, do another science. This will allow you to cover another field, and you honestly won't be missing anything by not doing ESD1. Jumping straight to ESD2 is a wise move.
The majority of the exam had questions like ''Why did this random oil rig blow up?'' with the answer being along the lines of bad planning, be careful next time etc. The exam is a complete joke. It's just silly common sense stuff wrapped into a subject which is supposed to be an ''introduction'' to engineering. The Matlab part of the course is taught horribly, so just skip to ESD2. You won't be behind anyone cause no one learnt how to use it properly in first semester.
I don't know anyone who did this subject and didn't think it was a complete joke. I think everyone got a shock when they realised how hard ESD2 is compared to the joke of ESD1 in first semester.
