How to Use These TSI Math Flashcards
1
Pick one topic
Use the topic dropdown instead of facing all 82 cards at once. Start with the topics you find hardest.
2
Flip, then mark
Read the front, say the rule or definition out loud, then flip. Mark Know it only when you can explain it, not just recognize it.
3
Practice right away
After a set, solve a few problems that use those rules. Flashcards build recall; worked practice turns them into test-day tools.
Best Order for Studying
If the deck feels like a lot, study the foundational topics first, such as numbers, fractions and percents, and exponents, then move on to algebra, geometry, and data, and review the test facts last. This moves from the skills every other topic builds on to the ones that appear in specific problem types.
Most Important Formulas and Facts to Know First
- Order of operations: the sequence that keeps every calculation consistent.
- Exponent rules: product, quotient, power, zero, and negative exponents.
- Fraction operations: and converting between fractions, decimals, and percents.
- Percent of a number and percent of change: the backbone of word problems.
- Slope and slope-intercept form: for reading and writing linear graphs.
- Area, perimeter, and volume: the core geometry formulas.
- The Pythagorean theorem: for right triangles and distance.
- Factoring and the quadratic formula: for solving quadratics.
- Mean, median, mode, and range: the four measures that summarize data.
- Probability of an event: favorable outcomes over total outcomes.
Common Mistakes These Cards Help Fix
- Ignoring order of operations and simply working left to right.
- Adding or subtracting fractions without a common denominator.
- Confusing area with perimeter, or surface area with volume.
- Flipping an inequality sign at the wrong time, instead of only when multiplying or dividing by a negative.
- Mixing up mean, median, and mode.
- Treating a negative exponent as a negative number instead of a reciprocal.
- Applying the Pythagorean theorem to triangles that are not right triangles.

Frequently Asked Questions
Is the TSI math test hard?
The TSIA2 math test is manageable if your algebra basics are strong. It is adaptive, so questions adjust to your level, and it is untimed, which takes away much of the pressure. Most students who struggle are rusty on rules like solving linear equations, working with functions, or finding area, so review those first with the flashcards.
How many questions are on the TSI math test?
The TSIA2 math College Readiness Classification section has 20 multiple-choice questions. If you score below the college-ready mark, you also take a longer diagnostic section that pinpoints which skills need work. Because there is no time limit, it pays to work carefully and check each answer on the 20 main questions.
What is the TSI math passing score?
On the TSIA2, a math score of 950 or higher on the College Readiness Classification section counts as college ready. If you score below 950, you can still meet the standard with a diagnostic level of 6. Scores run from 910 to 990, so aim comfortably above 950 by practicing algebra and data questions.
Are there free TSI flashcards?
Yes. This TSI math deck is free online, with 82 cards in 9 topics, including algebra, coordinate geometry, geometry, and data and probability, and 26 cards include a diagram. Filter by topic, shuffle for mixed review, and your progress is saved in your browser so missed cards come back.
