    For all highschoolers and University students having midlife crisis. Computer science is fun since you get to build stuff that doesn't yet exist or build something that you use and make it a lot better. Computer science is the study of computers involving complex algorithms and you'll be looking for stuff on the internet and stackoverflow alot. you don't have to memorize everything like a computer but you have to know how to make a computer memorize and process the information and perform the activities that you want it to.

      think of it as philosophical mathematics. there is not half truth. it is Either 0 or 1 and from that simulate addition, subtraction or every other function in your computer. your computer doesn't subtract. it only adds ( component call a full adder) now how do you divide only be using addition and numbers.

    Good video. Im in the least popular branch in CS, cs theory research. I'm glad you mentioned induction, if one dives into program verification, you'll see that induction is essential to doing any kind of proof because induction corresponds to recursion in programming. Induction on the natural numbers may not be interesting, but think about induction on your data types and proving properties about them. In fact, induction does not only apply to natural numbers, but any inductively defined set.

    I've been looking for a video that explains exactly what CS degree is about because Im not sure whether I should take up ux design or com science. I know myself to be someone that gets easily confused with numbers and need visuals/story telling to understand. Compared to the rest I'll say im slower with maths and science so I'll need more processing time than others. That's one of the reason I was scared to pursue CS but everyone was saying it's not really math but I had my doubts. Thanks for making this video because it clarified what they meant by "its not really maths its logic".

They test such irrelevant crap when it comes to Calculus 3, Rational Math, and whatever the current nomenclature of those curriculum happens to be; it's almost more of a test of "how much you care and are willing to get involved" which makes it seem harder than usual. The way it's tested, you might be completely stuck even if you understood what's going on, and they decided to ask a tricky question with no idea how to start it. Still proof by induction and those things does weed out a lot of people, and it does technically work.

      Yes, maths and programming is a decent chunk of the course. But I find there is more "theory" than anything else. I'm talking about how a computer *actually works*, and I think that's what you should focus on:
      System architecture
      Network Topologies
      Fetch execute cycle
      And programming and maths of course
      Market/Job stability seems to be great to be honest, even though the big companies are letting off a lot of people lately, there will only be a continuing demand for the skills in CS and smaller companies are hiring a lot of people. Not to mention start ups as well. In the UK, a computer science degree will take you 3 years if you get it right the first time. It is suggested you learn maths though, CS is embedded with lots of maths. I hope this was insightful :) look up a university curriculum for computer science to learn more and go from what the modules are on is my main advice. If a module is "Fundamentals of Programming", pick up a coding language like Python or Java as I'd suggest. Or something like AI, learn how AI works.
      That's my advice for you, good luck and let me know how it goes :))
