Final is part of the test category? true or false
Current grade:
What percent of your grade is the tests category?
Your current grade (in tests category)?
Total points in tests category currently?
Amount of points:
The grade you want:
You need a 32.0 on the final.

Notes

• Boolean, char, int, float, double are all primitive data types
• String, Array, etc. are non-primitive data types
• Learned to declare a variable that can be accessible and/or changed
• Learned how to store data as variables
• (=) is used to initialize variables or change its associated value
• Operators are + - * / %
• Compound operators are +=, -=, *=, /=, %=
• Increment/decrement ++ or --
