What our students have to say

I did the swift and iOS bootcamp in Georgia. It was incredible and totally worth it. I had only played around and pieced together iOS apps before I went to the bootcamp. After everything made so much more sense and I was able to create and publish new iOS apps with ease.

I used other online free courses to learn basic Kotlin and some advanced topics. It was nice to have the classroom setting, with the Kotlin Essentials course, to gain better-detailed knowledge. I do feel more confident with the basics of Kotlin, and I am looking forward to taking the more advanced courses.

I was able to start my research lab, HealthHawks, because Big Nerd Ranch gave me the skills to build software on mobile applications. I equip medical professionals with software that they test to be able to determine if it helps clinical outcomes. It is awesome. Big Nerd Ranch taught me how to change the world for the better, one line of code at a time.
