Envirsci 1c03 exam

Hi guys,

for those who the envirsci 1c03 final exam, how do you prepare for it? The prof just released practice problems only, no mc questions asking ab definitions or such. He also said that the exam will include GIS lectures, I am not sure if this is new this year.

I am afraid he is making exam harder since every single person i heard from told me it's exactly same as practice exam he released, which he didn't and i dont think he will.
