Parallax – The apparent displacement of an observed object due to a change in the position of the observer.

Do you feel stuck, confused, or lost? Are you studying as hard as you can without getting the results you want? Improving academic performance and increasing test scores often requires that students develop new approaches and apply novel strategies.
