Oliver is a professional standardized test tutor who studied at Northwestern University. He scored 1590/1600 (a score above 1540 is in the top 1% of test takers) on the SAT at age 16 and 1500/1520 on the PSAT (for which he was selected as a National Merit Finalist) and 36s on each section of the ACT (a perfect score).

Since 2018, Oliver has both prepared students for standardized exams as a freelance tutor taught for both small and large companies in the United States. He has helped dozens of people achieve their full potential. One of his students went from 1200/1600 to 1490/1600 on the SAT after just 15 hours of tutoring. He helped another go from 32/36 to 36/36 on the ACT after just 20 hours of tutoring.
