but the lecturer martin henz is a good one.
if he is still teaching this module this semester, prepare for
a lot of programming assignments. you should have a feel of his
teaching style if you have learnt cs3212 before.

cs3231 is difficult. the toughest module i ever read in soc. need i say more? :^)

cs3230 requires you to read a lot. the lecturer prof yuen is an
interesting person. but eating up a book of 600+ pgs within one semester is really painful. of course you can choose not to read, i didn't try, so dont ask me what the result would be if you dont read. besides the reading stuff, this module is ok.

cs3243 is the best module to fit your needs. as long as the lecturer is still prof tan.

i am not too familiar with cs3234.
