My friend's trying to figure out what her grade is in this class, because she wants to know if she should drop it. can someone figure it out?

The class adds up to be 100 points. here's how its broken up

Tests = 70% there have 3 tests. The first grade is a 62 (which is 20% of the 70%0 the 2nd test grade was a 63 ( which is also 20% of the 70%) and the 3rd test was a 74 (which is 30% of the 70%) (the highest test grade counts 30% not 20%)

other assignments in the overall 100 % grade

Article reviews (4% of the 100 all together points) This grade is a 100%

Position Paper (3%) this is out of the 100

Group Project and Presentation (15%) this is out of the 100 points

Participation (8%) of the 100%

everything adds up to be 100 %

What will her overall grade be? all assignments but the test, she has recieved full credit (100)

anyone know?
