I’m posting this for several sordid reasons. First is that I want to test whether WordPress has changed something in how pingbacks — a post linking to another post — get handled. Second is I want to get my post count for the month up from its pitifully low number. I’m at something like negative four posts for all April. Third is that oh, yes, it is about that time of the semester when a kind of student is trying to study just hard enough to get a 79.6 percent in their classwork. So they want to study up to an 86.2 on the final and not waste their efforts studying up to an 86.5.
So here’s a couple tables I set up years ago. They show, for some common breakdowns of how much the final exam is worth, and what your class average is before going into the finals, what you’d need to get a 60, 65, 70, 80, or 90.
If your case isn’t handled in the above examples, here’s an essay with the complete formula needed to handle any circumstance, including extra credit.
But seriously you can’t study yourself up to “just” enough to get your target grade for the course. Study to understand the subject and take the grade as it is.

I love how you put values in the table which are over 100.

Who am I to dash someone’s hope of getting extra credit, even if it takes a lot of extra credit?

I had the situation a couple of times in courses where I couldn’t pass a course. You had to pass the exam (which was worth 50%) to pass the course and my pre-exam score was 42%, so if I failed the exam, I failed overall, but if I barely scraped a pass in the exam (25/50), my total score would be 67% and a credit. Thus my minimum score over “fail” was “credit”, not “pass”.
(Yeah ,I got an HD, but then that’s me)

If I’m understanding the grade scheme put in ‘credit’ in-between failing and passing? That’s an interesting twist I haven’t encountered before, but I admit my provincialism. The places I’ve taught, or studied, have all been pretty similar.
