Actually useful and easy to follow

I’ve really enjoyed using Cosmo. The lessons make complicated topics like AI, business, and tech feel way easier to understand without making everything feel overwhelming. I like that it keeps things simple, interactive, and practical, especially when I’m trying to learn something new without reading a whole textbook at 2 AM 😂. Definitely a good app for learning at your own pace.

Awesome!

I’m currently applying for Early Career - Software Engineering at Roblox and Cosmo is helping me a ton with different coding languages!

Perfection

Diverse topics provided in a manner that you learn each day, but are not overwhelmed. I love it

Great learning app!

It is pratical just like other apps I know, but I wish it could have more energy per day to do the lessons.

Half-baked

Clearly an unloved and unimportant aspect to CodeSignal. All lessons feel like they were written by a dumb AI.

The paths are all basic and terrible. The exercises offer no value.

They glitch out and stop you progressing.
