TESC did horrible on final - can I still pass class?

[jam123]

Here's an update. So my grade for the final now shows 90%. I don't know how. Two of the essays worth 40% I left blank and the third I answered poorly. I did get all other questions correct. So I should have gotten a 40-60% grade. When I drill down into the exam it shows 40% but the instructor gave me a 90%. Is this a massive grade curve or an error? I guess I need to wait until the final course grade is recorded.

** fingers crossed for grade curve **
