Amara Johnson

Nursing · Georgia State

Nursing

I went from a C+ to an A- in pharmacology in one semester. Cody breaks every drug class into tiny lessons and quizzes me until it actually sticks. It finally feels like studying with a tutor who never gets tired.

Diego Martinez

Medical Coding · CPC Prep

CPC

I uploaded my whole CPC study guide and Mentivo turned it into a 6-week plan. The quizzes only ask about what's actually in my book, so I trust every question. I passed my practice exam with a 92%.

Priya Raghavan

Biology major · UC Davis

Biology

Cell respiration never made sense until Cody explained it with an analogy about a power plant. I ask for simpler explanations as many times as I need and never feel embarrassed.

Tyler Brooks

Computer Science · Sophomore

Computer Science

The personalized lessons follow my textbook chapter by chapter instead of jumping around. I save probably five hours a week that I used to spend making my own notes and flashcards.

Sofia Almeida

Psychology · Boston College

Psychology

The daily review queue knows exactly which theories I keep forgetting. My exam scores jumped a full letter grade and studying feels way less overwhelming now.

Marcus Lee

Accounting · CPA track

Accounting

Journal entries used to take me forever. Cody walks through each one step by step and then makes me try it myself. The mastery map shows me exactly what to review before the exam.

Hannah Kim

Pre-med · Organic Chemistry

Chemistry

Orgo mechanisms finally clicked. I love that every explanation points back to the page in my own lecture notes, so I know it isn't making things up.

Jordan Ellis

Nursing · NCLEX prep

Nursing

The streak and XP keep me showing up daily, which was always my problem. Twenty focused minutes a day beat the four-hour cram sessions I used to do.
