Falcon is a fast, secure, and reliable web application that helps schools and teaching staff conduct Node.js coding tests. Falcon aids lecturers in the grading process by automatically grading student submissions, thus saving time and effort. Students upload their attempts to Falcon, Falcon grades the attempt, and lecturers can download their submissions and review the assigned grade.
