How do you learn best?
Ready for a simple question that everyone should know like what your favorite color or food is. But of the 500+ people of all ages I have asked: no one does.
And it can be the difference between failing a class or getting an excellent grade. Not knowing can have another negative consequence by being labeled “ADD” or “ADHD.”
Are you a whole-to-parts learner or parts-to-whole?
