How do I become a scientist

Question: Is it possible for me to pursue a field in science with these grades? I'm sure most academic institutions would look past sophomore year and, hopefully, realize I have potential...

My grades -

Freshman year: 1st semester - B's and A's every class; 2nd semester - failed every class except health and intro. sci;

Sophomore year: 1st semester - failed ever class except Amer. history, biology, and English; 2nd semester - failed every single class;

Junior year(currently 1st semester, starting second semester Feb. 01): 1st semester - B's every class(online school);

>>3

I was taking 6 classes at the time, and yes, high school.

>>2

That's why I had to take freshman courses.

>>4

So it's possible, even with my grades?
