You can use the GPA Calculator on your BUIS page (https://registration.boun.edu.tr/buis) to enter a grade (letter grade or Pass) to any of the courses on your list and calculate your grade point average for the semester. You can even remove course(s) using the Remove button. You can go back to the original page by clicking Reset, and do as many simulations as possible.
This way you will be able to see the effects of Pass grades as well as the letter grades on your grade point average.
