Calculate average <grade_count> grades <remove_lowest_grade>:
	Create sum as 0
	Create min as +∞
	Repeat grade_index for each grade_count
		Read grade
		Assign sum as sum + grade
		If grade < min then
			min := grade
	If remove_lowest_grade then
		sum := sum - min
		grade_count := grade_count - 1
	Return sum / grade_count

Calculate expected grade:
	Return 0.3 * lab_average + 0.2 * quiz_average + 0.5 * exam_average
