For a long time now, MIT has its Open Lectures project. In it, you can scroll between many courses and even watch classes in some of them. This is a great study material that can help you out (for me it has helped).
I'll list some of the courses that have video resources:
- Linear Algebra
- Mathematical Methods for Engineers
- Mathematical Methods for Engineers II
- Differential Equations
- Physics I: Classical Mechanics
- Electricity and Magnetism
- Physics III: Vibrations and Waves
- Introduction to Biology
- Introductory Biology
- Principles of Chemical Science
- Media, Education, and the Marketplace
- Circuits and Electronics
- Computer System Engineering
- Introduction to Algorithms
- Principles of Digital Communication II
- Introduction to Copyright Law
- Atomistic Computer Modeling of Materials
- Symmetry, Structure, and Tensor Properties of Materials
