What modules should i do for further?

[jayleno]

matrices for sure , i do find networks rather easy at the start but it does get a bit confusing when when doing maximum flow, crashing and that
what do you guys reckon? what other options do i have?

Assuming you've done all your SACs already so putting in the time to learn another module won't be too much of a hassle; both geometry and graphs and relations are very easy to pick up so the choice is yours. Personally, I'd go with graphs and relations because I find it a bit more straightforward.

I do think though that your time might be better spent just revising and fixing the issues you have with networks rather than learning a whole new topic (or two!) and potentially having trouble with them as well.

just learn all modules and on the exam choose the easiest ones.
that being said, graphs and relations is by far the easiest thing u will ever learn.
