UWorld provide aspirants with best possible learning interface.

More than 5 million learners use UWorld to prepare for the USMLE, NCLEX, MCAT, CPA, CFA, SAT, ACT, AP, the bar exam, and pivotal tests in the USA. Video is part of how UWorld teaches, from 1,400+ CPA video lectures to 1,300+ MCAT lessons and 500+ expert-narrated medical videos built directly into its USMLE QBank answer explanations.

UWorld was running that library on AWS and had to stitch together separate services for storage, transcoding, delivery, and playback. As the catalog grew past 130,000 assets, UWorld wanted its own video platform: one system that handled everything instead of a set of AWS services its engineers had to wire together and maintain.

What challenges were they facing?

1. A fragmented AWS video stack - separate services for storage, transcoding, delivery, and playback
2. Heavy engineering overhead to build, connect, and maintain the pipeline
3. No single dashboard for content teams to manage, publish, and analyze 130K+ videos
4. Scaling secure, high-quality streaming for millions of learners across multiple exam verticals

So what worked?

With Gumlet, UWorld replaced a set of AWS parts with one video platform built to scale.

• An all-in-one platform for hosting, transcoding, storage, CDN delivery, player and analytics
• 37% decrease in cloud spend and media hosting
• 43% video optimization through AI-powered per-title encoding
• Automated, AI-powered per-title encoding with HLS and DASH adaptive bitrate streaming.
• Global multi-CDN delivery of 110 TB of video for uninterrupted course delivery.
• Easy to use Dual DRM, signed URLs and domain restrictions to protect premium exam-prep content.
• AI-generated subtitles and chapters to make long lectures more accessible
• In-dashboard video analytics - on a video level
• 99.95% uptime SLA and hands-on migration support from Gumlet

A Senior Engineering lead from UWorld had the following to say:

"Gumlet stepped in at a time where our CDN costs were spiking and our media pipeline was complex. Since implementation, it's been significant improvements on both fronts - our cloud spend has fallen, and maintaining our videos hasn't been easier."
