Question: what is a 1.6 gpa?
Answer: The national average for a GPA is around 3.0 and a 1.6 GPA puts you below that average. A 1.6 GPA means that you've gotten only C-s and D+s in your high school classes so far. Since this GPA is significantly below a 2.0, it will make things very difficult for you in the college application process.
