Student outcomes
Students who used the program to prepare for technical roles and academic presentations in English.
"I had the coding skills but my English was holding me back in interviews. I drilled with Crow Sentinel every morning before work. Three months later I passed the panel interview and got the offer."
"I could read English technical papers but couldn't talk about them. After four months, I presented my research to a room of engineers in English. Sentinel made me practice the pitch until I stopped second-guessing every sentence."
"Sentinel argued back every time I tried to explain my project. It pushed me to be precise. When I finally pitched to real people, I wasn't nervous. I'd already done it 30 times."
