Configuration Steps

Firstly you have to install Java 8 on your computer and set up MongoDB locally. After that, you can create a database called “lms_db” in MongoDB.

1. use lms_db;
2. db.createUser({user : “root”, pwd : “12345”, roles : [{role : “readWrite”, db : “lms_db”}]});
3. ./mongod –auth –dbpath ~/Mongodata/
4. ./mongo localhost/lms_db -u ‘root’ -p ‘12345’;
5. Then insert a teacher to db creating a user collection.  – db.User.insert({“email” : “rajithabhanuka1@gmail.com”, “password”: “123”, “role”: “TEACHER”, “regdate” : “2020-06-05”});
6. After that you can create new users and exams and assign them to students.

Limitations

• With the given time frame I could not be able to handle the errors.
• Maximum answer selection count is 5 (e.g your question only has  5 answers and student should select only one option)
