Question about W

I took 49 in first exam and 43 in second exam. My total grade is 65 C in calculus , There one more exam and final . The teacher said if you can maintain the grade to the end of the semester you will pass. My gpa is 2.5 . I am not sure if i can maintain it because there some topic that I am confuse about. do you recommend me to withdraw or continue . and if i take D it will hurt my gpa badly . what are my chances for pass?

You can easily calculate this yourself. Do it with a calculator.

How can i Calculate it and I don’t know how much grade i will get from another exam

Is your question:
