it's MORE beneficial to focus my efforts in more practical learning No. Not because "practical learning" is bad - indeed, it's as great as you say - but because the "practical learning" that you can find for yourself is available forever. Especially if you're naturally good at it. At this point, or at any other point in your life, all you need is Ramen noodles, a cheap laptop, a solid Internet connection and a credit card. Indeed, self-administered practical learning just gets easier with time, because you can move around and buy hardware and rent machine shops and own your own garage. But there are things you can't easily replicate outside school, or that are a lot easier to enjoy if you have credentials and go through channels. My personal favorite example is: Science labs. Colleges have real science labs! Which are really fun for practical learning! And which you can use as a student. I mean, I won't go so far as to argue that you should spend twelve years doing a Ph.D. and a postdoc just to get your hands on the femtosecond-pulsed UV lasers, the bounteous supplies of liquid nitrogen, the fully-equipped biochemistry labs, the cell-culture hoods and incubators, the specially-bred laboratory mice, they mysterious bottles of colorful liquids, the nanotechnology laboratory, the electron microscopes, or the particle accelerators. But I did. And I don't regret any of that! Yeah, I don't "use" my little pile of academic credentials at the moment. But there is more to life than just being "useful". Otherwise nobody would ever bother to, say, play Minecraft. I can learn math all I want through doing complex programming and creation of algorithms... So, are you one of those geniuses who has already aced the U.S. Mathematical Olympiad and then gotten bored with it? I have to ask, because such people exist, and if you are one I can't help you. But otherwise: Please tell me you've taken a serious high-school mathematics competition and been bored by it, because otherwise I'm not yet convinced that you know what you're missing. There is a lot of math that is not encompassed by "complex programming" or "creation of algorithms". A whole lot. More than I can understand. Not to mention the physics. Physics! In the hands of the right teacher, who is admittedly not easy to find, it's really a lot of fun.
