Elon Musk makes $43 Billion offer for private buyout of Twitter

Freshman chemistry at Tulane. I got a 35 out of 120 and got a 'D'. The high score was 52 and I think the average was 39. When no one gets it like that, is it the students, subject matter, or professor?
IIRC, in my case the professor gave us the wrong study guide. he apologized and graded on the curve. One guy got a 4 on the exam. Given that the course was 4 exams all weighted equally, I'm not sure how you recover from a 4.

The class was tough. It was 300-level class we had to get past for our degree and was designed to weed out pretenders. The professor was fair, the class just covered a lot of material and most of it was more hard science than your typical psych class.
