GradeTrain is an auto-grading and code feedback tool designed to assist educators with their programming project grading and review responsibilities. We're currently in Beta and are looking for feedback!
Great question! Some top tier universities do have things they like to say do automated grading, but even students and teachers I've talked to at Stanford, UC Berkeley, etc. say that they don't work well and are very difficult to use. They also don't have any of the awesome code feedback tools that GradeTrain does :)
Currently C++ and MATLAB. We'll be adding Java support during the next couple weeks. Our system is setup to handle new types of code very well - adding support for a language is as simple as installing the version of the language you want and adding < 40 lines of code :)
Python support is coming soon - which I'm super excited for because I love Python :)
If you get a sec, shoot us an email at contact [at] gradetrain [dot] com. Would like to hear more about how you'd be using these languages - we often find that our users have different ways of utilizing the language than we do as developers!
