USYD Science Electives Recommendations! (2nd/3rd year) (1 Viewer)

[zoehohoho]

Hey guys, I just finished 2nd year in bachelor of medical science and i really need to boost my WAM!
So just wondering if there's any 2nd year or even 3rd year science electives that are kind of like WAM boosters
Also i've been getting mixed information about whether if 3rd year units actually weigh more on the SciWAM?

Thanks!
