Contribution:The team successfully integrated the edX-platform with other necessary modules for comments, forums and grading. We have created ER Diagram for edX database which could be used by others for future developments and enhancements. We have performed experiments for testing django cache management and ease (AI) grading.

Ease repository allows anyone to use machine learning based automated classification which can work on both free text (essays, content, etc), and on numeric values.
