Time Savers on the ACT / SATMastery of content is the strategy that leads to success on the college entrance tests. Yet, another strategy – using shortermethods when approaching some questions – assists as well.MATHMemorize the formulas! (ACT)The questions become more difficult, so pacing is important.Use your calculator sparingly, only when necessary.Don’t spend too much time on any one problem; skip it and come back if time permits.Use meaningful variablesoA publishing company ships hard-cover textbooks in boxes that weigh 56 pounds each, andsoft-cover workbooks in boxes that weigh 35 pounds each. A shipment going to severalschools weighs 2604 pounds total and contains 60 boxes.
