Will I graduate from nursing school this semaster

You will if you work hard and get good grades.

If you are so unsure of your grades and your abilities that you are turning to a psychic, I would say it is doubtful.

If you were sure of your abilities, know you make passing grades, you would have no doubt that you would pass

You will only graduate if you have earned the grades. Since you're questioning it, it sounds like there's a good possibility that your grades are lacking.
