What it does
Calculator Academy groups calculations across science, construction, finance, food and everyday tasks, with an AI calculator-building option.
Calculator Academy offers free subject calculators plus a separate AI builder. Its WCPM worksheet asks for words attempted, mistakes and elapsed minutes/seconds, then reports correct-word rate and related fluency metrics. The formula subtracts mistakes from attempted words and divides by minutes plus seconds/60. Its guide distinguishes reading rate from comprehension and says appropriate norms depend on the assessment, grade, passage and scoring protocol. The builder accepts a description and offers testing, saving and sharing for custom projects; generated formulas still need checking against the intended relationship.
