How many questions are on the Praxis 5165?

The Praxis 5165 has 60 questions and a 150-minute (2-hour 30-minute) time limit. That works out to about 2.5 minutes per question on average — comfortable pacing for a candidate who's well-prepared, tight for one who isn't.

Question types

The 60 questions are a mix of formats:

Distribution by ETS content category

Probability and Statistics10%6
Discrete Mathematics7%4

Percentages are approximate — ETS doesn't publish exact item counts per form. Counts here are rounded to whole items out of 60.

What the timing means in practice

150 minutes for 60 items is generous if you've practiced under realistic conditions. Most candidates who finish prep with QuantegyAI report they had 20–40 minutes of buffer at the end. Where candidates run out of time is on the unfamiliar question types — particularly Discrete Mathematics graph-theory items and Probability and Statistics inference problems. Practice those under timed conditions before test day.

QuantegyAI's question coverage by category

We currently maintain 1,533 Praxis 5165 questions across the seven categories. That's roughly 25× the length of the actual exam, so adaptive selection always has fresh items to draw from at every difficulty level.
