The four kinds of number question
Pearson's Scope & Sequence chart lists Arithmetic Reasoning in the verbal part of the test at every level, A to G. Number Series, Numeric Inference and Number Matrix make up the Quantitative Reasoning cluster of the nonverbal part and start at Level D, grade 3. The chart gives no count for any kind, so each set here shares its questions equally.
What each kind asks here
A series question asks for the number that continues a row. An inference question shows pairs or groups of three joined by one rule and asks for the missing member. A matrix question hides one number of a three-by-three grid. Every explanation states the rule.
Questions and answers
Is there math on the OLSAT?
Yes. Pearson describes the test as measuring verbal, nonverbal and quantitative abilities, and solving arithmetic problems is one of the tasks its brochure names. It also calls the test a general indicator of academic ability that is not tied to specific content.
What kind of questions are on the OLSAT?
Pearson's chart names 21 kinds in five clusters: verbal comprehension, verbal reasoning, pictorial reasoning, figural reasoning and quantitative reasoning. Among them are Antonyms, Verbal Analogies, Figural Series and Pattern Matrix. This page practices only the four that use numbers.
Is there an official OLSAT practice test?
Pearson's product page lists its own printed practice tests by level, sold in packs of ten. The questions on this page are this site's own, and none comes from those or from any OLSAT test.
Is the OLSAT timed?
Pearson's product page gives the completion time as varying by level, untimed, with a maximum of 75 minutes. It gives no time for one kind of question, so this page sets no clock.
