I need to develop a plugin where a student will submit an excel spreadsheet to this activity submission. The plugin will then mark the formulas where the students specified where they are and check the output and give feedback to the student whether they are wrong or right.
For the lecturer they will add a key file which will be the memo. The plugin will compare the students submission to this file. The lecturer will also add the formula and correct output.
The most important thing the plugin must do is, the student will state where their formula and output is. The plugin will check the formula and output then give feedback as soon as possible.
I've been looking at the documentation and watching videos of development of Moodle plugins but still don't fully understand what is going on.
This is for my year project for my studies and need help.
