Academic notice screw-up

People who have been put on academic notice, what happened and how did you raise your gpa up?
Retook 2 classes that I scored low in (F and D), maintained all As for the next 2 semesters (16-17 credits each semester) got my GPA up to a 3.2. Alot of it was honestly just time management. Being honest with yourself about how much time an assignment will take you and getting it started. Google calendar was my savior. Logged in every single assignment that is worth anything the second I got the syllabus.
Prioritized, dropped some responsibilities(hard decision), and locked in.
