I wrote COS430 last year, and it was hell. To study all 900 pages are freaken mad! And to mention the price of the module, also freaken more mad!
I'm not sure about the module's layout this year. I hope its beter than mine. I managed to pass it on 59% first time
. So don't think for one minute it is not possible. Good luck to you, and hope all goes well. In my opinion if you do regular prep on INF425 here and there everyday, you'll definitly have a good go at the exam. It is definitely more student friendlier. But don't get me wrong, there is still a lot of work to do, but it will digest a lot easier than some other subjects that I have writing so far (like COS405 on tuesday - yack!). I can stil tast it!
