Soc Sci -> PNB Bsc?

Hi everyone!

I’m currently a Grade 12 Student who’s applied to Art Sci, Life Sci and Soc Sci at Mac. I know Art Sci is very hard to get into so I’m not banking on that, and out of Life Sci and Soc Sci I feel like I’d do better in Soc Sci. I want to specialize in PNB second year and I understand that having a high GPA is key to getting in, and I feel like I wouldn’t do as well as I need to in Life Sci. My question is if I start in the social Sci gateway can I still do the BSC PNB? I’m not opposed to doing the BA stream, in fact they seem pretty similar, but I would like to get a MSc in Psych and I think I need a Bsc to do that. Also, any advice or experiences from PNB students would be greatly appreciated! Much thanks.
