Sure thing south. It's a little tough to explain, but I'll try. Every two weeks we have an "assessment" (that's what we call exams), almost always on a Friday. We usually take the exam individually in the morning, then we turn them in and then take the same exact exam with your team or group later in the morning. If your group passes that exam with a 95% you get awarded points equivalent to 5% of the total points of the exam. What this means is that if your group passes, you need to have achieved 85% on that individual exam (because of the bonus "group points" awarded to you on the group exam)...if your group didn't pass with a 95%, you'll have to have gotten a 90% to pass the individual exam (no bonus "group points" are awarded...sucks to be you). Results are usually given by the afternoon, at which time we find out if we have to "remediate" that exam, or we get the following Monday off 😉. If you don't pass, you come back on Monday and retake the exam (different questions), and this time you don't have "group points" to help you out...it's a strict 90% to pass. If you don't pass this time, you have to take that part of the course the exam covers over the summer for one week (we call it "summer remediation")...that eats into your vacation time. You only have 6 weeks available during the summer for this, and if you didn't have any problems with summer remediation, that's your vacation time. If not, you have to go to school. You only have 6 weeks available, so if you blow more than 6 exams total, you'll be asked to withdraw from the program. We did lose a number of first year students because of that.
Oh, by the way, you don't get "held back" if you earned yourself summer remediation. Assessments are not like "final exams" for blocks. These assessments take place every two weeks regardless of the block being covered at the time. You can have an exam covering part of one block and part of another.
Believe me, it may seem difficult to comprehend, but if you've been through it just once, you get used to it rather quickly. Your pulse starts to quicken the weekend before the assessment, then you get a little more anxious every day up until the day before the assessment. We call it the "vicious cycle", because you repeat this every two weeks like clockwork.
