The numbers behind school, applications and paying for it
A GPA is a credit-weighted average, not a simple one — the GPA calculator gets that math right, and the target GPA calculator works backward from a goal to tell you what you need to average going forward. Before you commit to a school, the tuition calculator turns published averages into a real four-year cost of attendance, and the student loan calculator shows what a standard repayment plan actually costs in interest.
