The very definition of vegan is not exclusively food. Vegan is not using ANYTHING to do with animals; leather, fur, suede, products tested on them, products containing lanolin and other direct animal sources etc. . . Your friend is not vegan. There's too much to it and she wouldn't be in a hands on biology program.
- my cousin was a vegan and she quit university when she found out about the animal lab. o-o
But Oly, it is important to pace yourself. Eat right and sleep right. These two things are of sole importance to a good routine which will get you the grades and outcome you wish for in university. Waking up at 7 am and working straight through till midnight will only 1. kill you 2. make you hate university 3. get undesired results. I know you're a good student and that you have the potential to come out on top of your class but you really need to lay out some personal goals in terms of when to eat, what to eat, what hour to cut off homework/studying and a time in which you can do some leisure activity/sleep.
Trust me, I did a research/writing degree and in 4 years I learned all the bad ways to get through. I still procrastinate but I know how important diet and rest are to a learning mind.
Also, Missed my opportunity this morning to do Orientation at my uni for all the first years. I realllllllly wanted to do it but for weeks I couldn't get a hold of the coordinators to confirm my spot. Now I'm sad.
