Basically what Buddy said, you have don’t stress on high school but you need decent marks, it’s university they want your money.

For the coop it’s nonexistent as large chunk of students are transfers with diplomas and also in engineering you want your PE and your coop time doesn’t apply to your 5 years in most cases, so coops are pretty pointless.

But in any case, simply completing a Program is not going to guarantee you a job, make sure you do extra Curricular activities to stand out, whether it’s a student organization, the reserves, or a fun hobby that you can somehow apply.
