The mystery mark enrolling into a Bachelor degree is just a joke people make. If you are a few points off and didn't put EAS, they will still most likely accept you. UWS is the university that makes people happy.
A few minor differences. One of them being what will be said on your graduation papers. Having no background knowledge in the subjects you listed wont make it a lot harder. Make sure you have a good amount of mathematics skills and knowledge. Just make sure you know how so write and structure...
