ACT Math

Forty-five questions in fifty minutes, one section, four choices each, no formula sheet. About three fifths of it is high-school mathematics across five domains, and the rest is arithmetic from earlier grades asked at a question a minute. Six domains, weighted here as the test weights them. Start with the diagnostic; it will tell you which of the nineteen topics to read.
