Gradescope is a tool which is particularly useful and popular for Science and Engineering instructors who need students to submit hand-written assignments (e.g. hand write formulas, draw diagrams and charts)
It allows for handwritten assignments to be graded digitally, and for multiple graders to collaboratively develop and implement their grading rubrics. It supports problem sets and projects as well as worksheets, quizzes, exams, and papers.
