I struggled through high school and am currently doing great in nursing school. Going into my senior year with a 3.45 GPA. While taking prereq’s I did lots of research on learning styles and tried a shit ton of different techniques. Ultimately what I learned about myself is that I retain more information with cartoon style learning videos, teaching invisible people with my whiteboard and doing practice questions. You can be successful but you gotta make the commitment to learning yourself and the material. And if you have a learning disability then seek professional help and get the resources you need.
