HI
i am planning to create a SQL IDLE using asp.net and C# . in that i am going to implement 4 modules :

1) Student Login module
2) Student Teaching Module (like w3schools.com )
3) Student Feedback module (personalized feedback )
4) correction module

Now my problem is that i implemented first two modules but i cant implement 3rd and fourth module .

Correction module :

If someone types "selects" instead of "select" , then it will show error and give recommendations & feedback .

pls help me to complete all modules .
