Exam Developer - Math, Quant, Logical Reasoning

We have an opening for a part-time contractor to review test questions.  The questions are on math, quantitative, and logical reasoning topics.  You will be assigned a group of items to review, and you will send back any issues you find.  The work happens every 6 weeks or so, with 10-20 hours each time.
These items are for a post-secondary admissions exam, so imagine the questions being more about interpreting tables of data, rather than standard K-12 math curriculum.
Requirements Bachelor's degree in math, data science, finance, or other quantitative subject.
You must live in the USA for this position.
Preferred Experience with exam development and assessment
Compensation: $30-40/hour
