Dear Dr Makham, I have a difficulty in understanding how the value of MSY mentioned in the slide at 16:33 seconds is derived. Could you please explain the break up of this calculation as me and my students both really didn't figure it out. Thank you for your support.

Hi, I’m a DP2 student who’s going to take the may 2023 exams. I’ve been taking chemistry until now but I can’t seem to get past a 3 no matter how much is study. Do you recommend switching to ESS as I need a 4 in my science for uni, or is it too late to change now?
