General Education Math on the LET rewards calm recall under time pressure. You do not need every formula from four years of coursework in working memory — you need a shortlist you can retrieve without panic, then apply to stems without arithmetic slips.
This guide is independent study advice from Techsider Solutions / LETReady. It is not affiliated with the PRC and does not guarantee a passing score. Confirm current coverage against your review materials and official notices.
Who this is for
- First-time LET takers rebuilding GenEd Math after a long break from formal coursework.
- Retakers whose mocks show Math as a primary fire subject.
- Examinees who know “the idea” but freeze when a formula will not surface.
How to use this shortlist
Memorize the form, then immediately solve three mixed items that force the formula into a stem. Spaced retests beat one marathon night. Pair this article with topic practice:

1. Percent, ratio, and proportion
Why it matters
Many GenEd stems disguise percent change, part-whole relationships, or recipe-style proportions as word problems. If the skeleton “part / whole = percent / 100” and “a/b = c/d” are automatic, you free working memory for reading carefully.
Drill cue
Underline what is the base. Misidentifying the whole is the most common miss — not the arithmetic.
2. Linear equations and simple systems
Why it matters
Age, work, and mixture-style items often reduce to one or two linear relationships. Keep slope-intercept intuition and substitution/elimination as muscle memory for two-variable cases your materials emphasize.
Drill cue
Define variables in one line before writing equations. Rushed symbol choice creates consistent wrong options.
3. Perimeter, area, and basic volume
Why it matters
Geometry items punish formula fog more than conceptual depth. Rectangle, triangle, circle (as your scope requires), and rectangular solid formulas should be instant.
Drill cue
Sketch even when the stem looks simple. Labels prevent unit and dimension mix-ups.
4. Mean, median, mode, and simple probability
Why it matters
Data literacy items appear across GenEd. Know how outliers tug the mean, when median is preferred in your materials’ framing, and basic favorable-over-total probability language.
Drill cue
Slow down on “at least / at most” wording. Paraphrase the event before computing.
5. Exponents, radicals, and scientific notation (as scoped)
Why it matters
Science-adjacent GenEd items and pure Math stems both use compact number forms. Product and quotient rules for exponents, plus converting to/from scientific notation, save minutes.
Drill cue
Rewrite the expression before simplifying. Hidden parentheses in stems cause silent errors.

FAQ
Should I ignore advanced topics?
If your materials include them and mocks miss them, keep thin contact. The shortlist is a floor, not a ceiling.
Calculator assumptions?
Follow the rules of your actual testing conditions. Train the same way you will sit.
