Core calculators
Five frequently useful tools, each with a concrete example of the result it can produce.
Final Grade Calculator
Estimate the exam score or remaining grade you need to reach your target final grade.
Example: A 78% current grade at 70% weight needs about 91.3% on a 30% final to reach 82%.
GPA Calculator
Convert course grades and credits into a term GPA or cumulative GPA estimate.
Example: An A in a 3-credit course and a B in a 1-credit course average 3.75 on a 4.0 scale.
Attendance Calculator
Check attendance percentage and see how many classes you can miss or need to attend.
Example: Attending 18 of 20 classes is 90%; one more absence changes it to about 85.7%.
Weighted Grade Calculator
Calculate a course grade from assignments, exams, projects, and other weighted categories.
Example: 80% at 40% weight plus 92% at 60% weight contributes 87.2% overall.
Study Time Calculator
Plan study sessions from deadlines, available days, subjects, and target study hours.
Example: Twelve hours across six available study days becomes a two-hour daily target.
