Somewhere on this page [under my photograph, if you are on a PC] is a link to a UKy OneDrive folder with helpful lessons for introductory physics. There is a lot of content online, and you might find free textbooks whose content are similar to you class's material. Find what works for you, but make sure you are not finding solutions to problems which are nearly identical to the problem you are solving at the moment. In the linked folder, I solve some specific problems, but talk quite a bit about the tools used to solve them and how you can use the tools to solve other problems.

Some of the content is only understandable to calculus-based physics students. If you are not in calculus-based physics, don't worry about it, skip over it.
