I could do it with a bit of time is there any means to contact you privatly?
Create an application that allows a teacher to enter
three test scores for each of his/her students and create a list of average scores for each student.
First of all the application should ask for total number of students. Then the application should calculate each student’s average test score and assign a letter grade based on the following grading scale 90 and above = A, 80-89 =B, 70-79=C, 60-69=D, and Below 60 = F.
Once the user clicks on Enter Data button, the application should ask for total number of students. Then ask for students name and the 3 test scores. All the data should be listed in a listbox
