Sarah M.

Licensed Architect

AREprep

The Challenge

Sarah failed the PPD division of the ARE twice using traditional study materials. Months of passive reading and generic practice questions left her frustrated and doubting whether she could pass.

The Approach

She switched to AREprep and committed to a focused 8-week plan built around active recall. Every day, she worked through flashcards targeting her weak areas and completed timed practice exams that mirrored the real test format and difficulty.

The Result

Sarah passed PPD on her third attempt with a comfortable margin. Riding that momentum, she passed her remaining 3 divisions on the first try. Her total study time dropped by 40% compared to her earlier attempts.

Marcus J.

PMP Certified Project Manager

PMPprep

The Challenge

Marcus was working full-time and raising two kids. He could carve out only 45 minutes a day to study for the PMP exam, and he knew he could not afford to waste any of it on ineffective methods.

The Approach

He used PMPprep flashcards during his commute and lunch breaks over 12 weeks. The active recall format let him study in short bursts without losing continuity, turning dead time into productive review sessions.

The Result

Marcus scored Above Target in all 3 domains on his first attempt. By focusing every session on retrieval practice instead of passive review, he made the most of his limited time.

Diana L.

Registered Respiratory Therapist

NBRCprep

The Challenge

As a new graduate, Diana was anxious about the TMC exam. She felt overwhelmed by the breadth of clinical knowledge required and worried that classroom study alone had not prepared her for real-world exam scenarios.

The Approach

She used NBRCprep's clinical scenario practice and flashcards for 6 weeks, focusing on the patient-based questions that simulate actual clinical decision-making. The active recall format forced her to think critically rather than simply recognize answers.

The Result

Diana passed the TMC with a score high enough to earn the RRT credential on her first attempt, skipping the need for the separate Clinical Simulation Exam that many candidates require.
