You might struggle at McMaster University with an 81% in high school studying engineering, but that doesn't mean you can't do it. I am not sure what average you need to get into engineering at mac, but don't base your performance in university on your high school average.
What i am trying to say is, don't get disappointed and feel that you can't do it. You have plenty of time to raise your average up and get accepted into engineering here at mac.
Another thing, if you don't get accepted at mcmaster for engineering with an 81, there are other universities that will take you into their engineering program. If you are afraid that you are not going to do well at mcmaster, you can probably do better at different universities. That's why i think it would be a waste of time if you go to college and then come to engineering. I am actually surprised that you are even thinking of going to college even though you have an 81 so far. If you told me that you have 60s or 70s and thinking of going to college, i would say you have a point. But you have an 81%, don't give up easily. I am not against college or studying in college, but i don't see a point of you going there.
As i said earlier, mcmaster is not the only university that offers engineering, there are other universities that will take you into their engineering program. If you live in Hamilton, i can see why you want to go to mac, and not a different university. You should never base ANY decision on things that are not important or things that will get in the way of other more important things. If you live in Hamilton you can apply to ryerson and go there for engineering. Their admissions average is lower than that of mcmaster, and you don't have to live in Toronto. You can simply commute, it's tough i understand, but at the end of the day you are getting a degree in engineering. I have friends from Hamilton who commute everyday and are studying engineering at ryerson.
Look, it's November and you have a lot of time to improve your grades and come to mac for engineering. Don't ever give up or let someone put you down..you want engineering? Fight for it!
Engineering is hard, but that doesn't mean that people don't do well in it. There are people with perfect GPA's in engineering, and there are others with good grades..why am i saying this? To show you that hard working and dedication will get you good grades, yes even in engineering :p
One thing to note here, i have friends who got 80s in grade 12 and did well in engineering at mac. Doing well in engineering depends on how well you
manage your time and how hard you work. It does not depend on your grade 12 average.
If you don't make it to engineering at mac this year, you can go to ryerson for one year, work really hard and then come back to mac.
One last thing, i don't want you to think that engineering at other universities is easy. Engineering at ryerson for example is a bit easier than our program here at mcmaster. It's a little bit less challenging, that's all. Engineering is engineering anywhere you go, it's just that some universities have a more challenging program.
I don't see a point in you going to college, you have a decent average, keep up the good work, try your best and we hope to see you next year here at McMaster
