This is my code and I am importing a file and need to print out the number of students in the class, the average test score, the highest and lowest grade, and how many received each letter grade. I will attach the text file I imported.
My output says there is only 33 students and there should be 35. It was outputtingGrades.txt 35 before I put in all the if statements to add to the number of each grade. Then it changed to 33 and I'm not sure how to fix it.
