Answer 1

You are overriding your "total" variable in each interval with double the grade value.

var grade=parseInt(g);
 var total=grade+grade;

should be changed to

var grade=parseInt(g);
 total=total+grade;

Also, you need to initialize the "total" variable in the beginning of your code. See demo code: http://jsfiddle.net/56ouvan3/1/

I would also recommend some input validation (such as checking that the number of grades requested to average are greater than 0, all grades are positive, etc.)
