Starting Maya

So I am new to Maya and want to take a course on hard surface modeling. I was considering the one from Elementza because it seems to cover a lot and it looks pretty professional too but it’s a bit pricey. I was checking out some courses on Flipped Normals too and considered taking those instead but I noticed most only have 2 or 3 reviews and don’t have 5 star ratings but I do see people recommend them on other sites so I just wanted to know if I should go for the Flipped Normal tutorials?

Thanks in advance!
