Praxis 5165 Practice Test — Adaptive Math Content Knowledge Prep
Targeted, adaptive preparation for the Praxis Mathematics: Content Knowledge exam (test code 5165). 1,500+ practice questions across all seven ETS content categories, with Item Response Theory placement so you stop wasting time on what you already know.
What the Praxis 5165 actually tests
The Praxis 5165 is the standard mathematics content-knowledge exam used for secondary mathematics teacher licensure in most U.S. states outside Texas. It is 60 selected-response and numeric-entry questions in 150 minutes, computer-delivered, with an on-screen graphing calculator. The current passing score depends on your state; most states set it between 150 and 160 on a 100–200 scale.
ETS divides the exam into seven content categories. Our adaptive engine places you in each category independently — so a strong calculus background doesn't bury weak discrete math, and vice versa.
Question coverage by ETS category
How adaptive prep is different
Most Praxis 5165 prep is a static question bank or a 600-page review book. You read the chapter, attempt the end-of-section problems, check the key. That works if you already know your gaps. Most test-takers don't — and the time they burn re-doing comfortable material is exactly the time they needed for weak topics.
QuantegyAI runs the same Item Response Theory model used by the real exam vendors. Every answer updates an estimate of your skill on each competency. The next question is then drawn from your upper bound of mastery — just hard enough to confirm or revise the model. After about 30 placement questions, you have a calibrated ability estimate per category and a personalized study plan.
Who built this
QuantegyAI was built by Dr. Mienie Roberts, a mathematics professor and an active reviewer for the Texas Instructional Materials Review and Approval (IMRA) process. Every question in the bank is authored or vetted by a working mathematician — not crowd-sourced or scraped.

Frequently asked questions
Is this the same as the Praxis II?
Yes — "Praxis II" is the older umbrella name for ETS's content-area Praxis exams. The mathematics content-knowledge exam you'll register for is officially "Praxis Mathematics: Content Knowledge (5165)".
Does QuantegyAI cover the older Praxis 5161?
No. ETS retired the 5161 in September 2022 and replaced it with the 5165, which has slightly different category weights and adds Discrete Mathematics as a standalone category. Our question bank targets the current 5165 framework.
Can I use a graphing calculator on test day?
A calculator is built into the testing interface — you don't bring your own. Our practice mirrors the on-screen calculator behavior so you're not surprised by the workflow.
How long should I prepare?
For most test-takers, 4–8 weeks of consistent adaptive practice (3–5 sessions per week, 30–45 minutes each) is enough to reach a passing score from a typical undergraduate math background. The placement test gives you a calibrated estimate of how far you are from passing on day one.
