ACT Score Calculator - Calculate your ACT composite score (1-36) from your English, Math, Reading, and Science section scores. The composite is the average of the four sections rounded to the nearest whole number, and this calculator shows you exactly how the rounding works: how many section points you need to reach the next composite, how much cushion you have, your national percentile rank, College Readiness Benchmarks for each section, your STEM score, and the equivalent SAT total score. A visual rounding number-line and a "next-point leverage" advisor show the cheapest path to a higher score.

AP Score Calculator - Predict your AP exam score from 1 to 5 using your multiple-choice (MCQ) and free-response (FRQ) performance. Choose your AP subject to apply its real score curve, see exactly where you land on the 1-5 composite number line, find out how close you are to the next score, and get a leverage advisor that tells you how many more MCQ questions or FRQ points you need to bump up your score. Includes a step-by-step breakdown, section contribution chart, and AP score meaning guide.

Attendance Percentage Calculator - Calculate your attendance percentage from classes attended and held, then see exactly how many classes you must attend in a row to reach 75%, 80%, 85% or any custom target — or, if you are already above it, how many classes you can safely skip (bunk) and still stay eligible. Optionally enter the total classes in your term to project your final attendance and your remaining skip budget. Includes a visual gauge, a target ladder, an end-of-term projection chart and a step-by-step breakdown.

It also classifies your result into the standard division/class (Distinction, First Class, Second Class) and shows an animated CGPA-to-percentage mapping ruler with a step-by-step breakdown. Supports 10-point, 5-point, and 4-point scales plus a custom multiplier.
