Locked Grades and a Real GPA Range

Once some grades are locked in and others open, your real semester GPA is not one number, it is a range bounded by the best and worst outcome.

Partway through a term, some grades are already effectively decided while others are still genuinely open. Treating your GPA as a single guessed number at that point overstates how much you actually know; a range built from your locked grades plus a realistic min-to-max for each open course is more honest.

A GPA range, not a single guessed number, reflects what is actually still uncertain mid-term.

A single guessed GPA hides real uncertainty

Picking one number for an open course and treating the resulting GPA as fixed makes a genuinely uncertain situation look more settled than it is. A range built from an honest minimum and maximum for each open course communicates the real uncertainty instead of hiding it.

Locking a course collapses only its own range

As a grade is finalized, that course's contribution becomes fixed and its range collapses to a single point, narrowing the overall GPA range without affecting any other still-open course's own range.

A narrow range is more useful than a wide one, but both are honest

Early in a term, before much is locked in, the range will naturally be wide; that width is accurate information, not a flaw in the calculation. As more grades finalize, the range narrows on its own toward your eventual actual GPA.

Key takeaway. Use a realistic minimum and maximum for each open course, not a single guess, and recalculate as grades lock in. A range is a more honest mid-term answer than one guessed number.

Frequently asked

How do I set a realistic minimum and maximum for an open course?: Base it on your actual current standing in that course, such as your currently possible best and worst outcomes, rather than the theoretical full A-to-F scale, which is almost always wider than what is realistically still possible.
What if I want a single number instead of a range?: Use a named-scenario comparison with one specific assumed grade per open course instead; a range answers "what is possible," while a scenario answers "what if this specific thing happens."
Does this replace a normal GPA calculation once the term ends?: No; once every course has a final grade, use a normal GPA calculation directly. A range is specifically for the mid-term period when some grades are still genuinely open.
