Help Choosing Units

Hi! I just wanted some advice from people who have taken these units, FIT 3171, FIT 2004, FIT 2099, as the course adviser recommended I take these 3 and an elective, Im thinking of taking a language as an elective, or if anyone has any recommendations for minimal study HD electives Im all ears:)

From people who has taken this unit do you think this combination is manageable? Ive heard FIT 2004 is really difficult, I just did FIT 1008 , FIT 2014 and 2 econs electives so how do you think it compares to that? I had to solo both my FIT 1008 group projects so it was a really hectic sem for me

Any advice and help is appreciated thanks!
