I have recently discovered this YouTube channel https://youtube.com/channel/UC-ssgSLLaFYn1LARgEAqWBg which contains lots of mathematical physics and mathematics courses. I am not a graduate student. So I don’t understand this courses. If anyone out there want to review this material, and approve these courses are graduate level, would be much appreciatedcourse.
