Improvements

1.Instead of showing student details on the Transcript Text Field we can use popup for showing them whenever required.With this we able to save space also which is a good and required approach for designing UI.

2. We can replace the buttons of Average,Transcript,Delete,Reset and Exit with colored ones which will capture the attention of the users to take action which he wants.

3.We can take off the showing of static validation of Please enter marks of 0-100 and can implement with dynamic validation of giving the user a message whenever he enters the value.

4.We can wrap up the Average,Transcript,Delete,Reset and Exit options with the name of Actions of left side menu(can be expand) which will save the space and good look and feel.

5.Showing of the details can be taken in tabular form in Pop up(Modal) which will give good attention to the user and also it is appropriate and proper because the marks can be nicely visible in Table Format which generally followed method.

6.Predicate and Average can be distinguished with different color so that it can vary other fields.

7.Student Name and Student Id can be taken in Header Format like Student Grading System with standard Font Size.
