+4. PROJECT: Grade calculator
+Every week ends with a project you have to build on your own. Instead of getting clear-cut instructions, you'll get a list of criteria that your project needs to measure up to.
+
+In this project you'll write a function that calculates grades, based on the American grading system! Let's say a student did a test and they got a 60 out of 100, this function will:
+
+convert the score into a percentage
+calculate what grade corresponds with that percentage, and
+shows in the command line the result: the grade and the percentage
+In this example this is what we would expect the function to return in the command line:
+
+You got a D (60%)!
+When writing the function, make use of the following grade scores:
+
+Grade A (90% - 100%)
+Grade B (80% - 89%)
+Grade C (70% - 79%)
+Grade D (60% - 69%)
+Grade E (50% - 59%)
+Grade F (0% - 49%)
+These are the requirements your project needs to fulfill:
+
+Make a JavaScript file with a name that describes its contents
+Use either a switch or if/else statement
+Write at least 2 comments that explain to others what a line of code is meant to do
+Make the return value of the function a template string, so you can insert variables!
+Use node from the command line to test if your code works as expected
+Good luck!

+All characters must be numbers
+At least two different numbers should be represented
+The last number must be even
