Need help with shell script

Question

I am a total newbie to Shell Scripting so please bear with me. I need to create a shell script called script1 that will calculate and then display letter grade of ABC2345.

1. Read in the following grades from keyboard:
   • Assignments 40%
   • Test1 15%
   • Test2 15%
   • Final exam 30%
2. Calculate and display the number grade using the weight of each factor above
3. Convert the number grade to letter grade using the table below:
   • Number Grade Letter Grade
   • 90 - 100 A+
   • 85 - 89 A
   • 80 - 84
   • 77 - 79 B+
   • 73 - 76 B
   • 70 - 72 B-
   • 67 - 69 C+
   • 63 - 66 C
   • 60 - 62 C-
   • 57 - 59 D+
   • 53 - 56 D
   • 50 - 52 D-
   • 0 - 49 F

Any help would be appreciated :) Thank you!

Well ill go ahead and give you a quick idea... but no logic ;)

i would recommend using a "case statment" and a "while read" or "for" loop... google those items and you should have everything you need.
