Yes, MPE is required of all students. There is a practice exam - highly suggest he takes it - the material is often from the past for more advanced math students so a review is needed to jog the memory. I don’t have a current new applicant, but I’m sure someone will chime in as to notification this year. You can retake the exam if needed after a waiting period but prior to the NSC date. Here’s a discussion from March with more info – http://talk.collegeconfidential.com/texas-m-university/1971152-math-placement-exam-question.html
