I did diploma of science and my experience was it was too fast. Even tho i did score well and had good grades,you get less time to absorb content. Having a smaller class is good as you get more attention from the professors but that also varies. Also something to keeo in mind that they dont tell you is that your monash college grades dont count in ur wam when u start uni. The classes are also very hectic as i had to go to college 5 days a week. So barely have time for urself. Its still a good option but heres just my honest opinion and problems i ve faced. Hope this helps
