final_grade_neededread-only | Use this when a student asks what score they need on a final exam (or last assignment) to reach a target grade, given the current grade and how much the final counts. Returns the needed percent, whether it is secured or out of reach, what a 0 and a 100 would leave, and the need for every letter. Works with percents (current_grade_percent + final_weight_percent) or with points (points_earned_so_far, points_possible_so_far, final_exam_points). Do not use it for a weighted average of categories. |
gpa_calculatorread-only | Use this when a student wants their GPA from letter grades and credits, high school (honors +0.5, AP/IB +1.0 on passing grades, weighted and unweighted) or college (credit hours, unweighted). Returns unweighted and weighted GPA with the points of each course. Credits default to 1 (hs) or 3 (college). Do not use it for a single test grade or for a school-specific formula such as UC or LSAC. |
grade_calculatorread-only | Use this when a student or teacher wants the percent and letter grade for a test from the number of questions wrong (or correct), e.g. "7 wrong out of 40". Returns the percent, the letter on the chosen scale, how many more correct answers reach the next letter, and optionally a chart of every possible number wrong. Do not use it for a final-exam target, weighted categories, GPA or test scores. Needs only numbers; never ask for names. |
grading_scale_factsread-only | Use this when someone asks what a grading scale is: the 10-point scale (A 90-100), the 7-point scale (A 93-100), the plus-minus scale with GPA points on 4.0 and 4.3, or the College Board percent-to-GPA table. Returns the cut-offs, the named sources and the date they were checked. Use it instead of answering from memory; there is no national scale and schools differ. |
test_score_calculatorread-only | Use this when a student wants a score from a published practice test: SAT (College Board digital practice tests 4-11, correct answers per section to score ranges), ACT (practice tests 1-4 and the National test, correct answers per section to scale scores and Composite) or MCAT (four section scores 118-132 to total and AAMC percentile). Returns the score with the source table and fetch date. Not for official score reports, other tests, or predicting a real exam. |
weighted_graderead-only | Use this when a student wants the weighted course grade from categories such as homework 20%, tests 50%, final 30%. Each row has a score (percent, a fraction like 45/50, or a letter) and a weight; rows without a score count as still open. Returns the weighted average, the letter, how much weight is graded and open, and optionally what the open part must average to reach a target grade. Do not use it for a single final-exam question without categories. |
