Well, I knew L3 wouldn't be easy but I've ground to a halt at this assignment. 
I'm stuck at Question 4 Assignment 7. I dont even know where to start to answer this one!
If anyone could offer a nugget of wisdom to get me going again i would be eternally grateful!!!
The next 2 assignments in this course fill me with dread and i just want to get them done asap!
Thankyou in advance
