This site has helped me improve in Physics as to take the exam. The best part is that it takes you through each step of the problems and gives you worked answers in a way you learn from your mistakes, instead of being left in the dark. It helps a lot for studying.

StudyIB.net helped me see IB Physics in a completely different way that really helped me prepare for the exam.
