The kahn academy website has amazing courses for all sorts of things, maths and science alike.
If you are looking to increase your critical thinking capabilities then just think, it is something you will have to do yourself. This place is not the place to get the best advice about this stuff because /sci/ is actually a pretty dumb board. Ironic isn't it?
Do you seriously think actual professors and intelligent people will spend their time here? It is why I am here anon.
Sure there may be a few galaxy brained anons here and there but most of this board is people flashing their online IQ test scores to feel special and make all of their threads incredibly vague and retarded so nobody understands the generally simple concepts they are putting across. Again, to make themselves feel smart and special.
GL out there anon and think for yourself.
