ASSIGNMENT: The calculation of the grade is based on the following rules: Quiz Average = simple arithmetic average of the highest 4 quizzes. Course average is a weighted average, as follows: 50% for Quiz Average, 15% for the MidTerm, 10% for the Problems, 25% for the final exam. Letter grade is based on the standard 90/80/70/60 brackets, with rounding .5 up to the next highest whole percent. Except that: a student who received 90 or better on each of the following: Quiz Average, Midterm, and the Problems (that is, on each of those 3 items must be 90+ after rounding) gets an A and did not have to take the final exam. In such a situation the course average is just the arithmetic average of the three components (Quiz Average, Midterm, and Problems scores). The Clear button resets the form and puts the focus back in the Student Number box. In this program the javascript should check that all values have been entered and that the numeric values are between 0 and 125 for each score. If any bad data is detected, the javascript should inform the user and return the focus to the input box causing the problem. Please note that you should validate the student number as following the STLCC format: capital A followed by exactly 8 digits, which must not all be zero. An empty last or first name field is also a validation failure. The make-up quiz input field, however, is the only one on the form which may be left blank. (If it is, assign a score of zero to that value for the purposes of calculating the quiz average). All javascript for this application should be put in a separate student.js file containing the functions needed to calculate the student scores and grade i am lost on how to code the student number and how to make the final optional.
