Best online course for 3D game character modeling

jaski

I’m looking to do an online course but I’m confused which course to choose. I’ve checked out CGMA, Game Art Institute and CG Spectrum. All these course seem great but I would like to know if anyone here has an experience with these courses. I’m not a total beginner and have some experience with modeling using Maya and Zbrush but would like to enhance my skills and eventually have a few pieces for my portfolio. Which courses do you recommend are worth the money and time? I would love to be mentored by a professional that can teach me the right way to go about creating characters for games.
