What online videos for physics would you recommend?

Hi, im a college student in a second semester calculus based physics. On Wednesday we have our next test and im still struggling on the material. This test will be covering
Current and Resistance
Direct-Current Circuits
Magnetic Fields
Sources of the Magnetic Field
Faraday's Law

Those are the names of the 5 chapters, they all have your usual subtopics (ex. Kirchoffs Rules, Amperes Law ect.)

Does anyone know of a video series online that can help me get a better understanding on how to approach a problem? I've watched all of Khansacademy but his problems are way to basic.
Additional resources or recommendations would be great! Thank you for taking the time to read this and i really appreciate the support. Heres a question from last semesters exam to help give an idea of the level of problems!

A Long, cylindrical conductor of radius R has non-uniform current density that varies according to J=br^2, where b is a constant. Find the magnetic field a) outside and b) inside the conductor.

Oh and we have 5 problems like this 2 do in 50 minutes so i guess its not the difficulty of the question, its the amount of time allowed to think about the approach.

Check all of those links properly, some look similar but they all have different content in
some form or another.
