Learn using videos, interactive exercises, and in-depth articles in math (arithmetic, pre-algebra, algebra, geometry, trigonometry, statistics, calculus, linear algebra), science (biology, chemistry, physics), economics (microeconomics, macroeconomics), humanities (art history, civics, finance, US history, US government and politics, world history), and more (including computer science principles)!
I recommend checking out CS Dojo, TheNetNinja, and Harvard’s CS50 YouTube channel. If you don’t have time to search for a perfect coding video or channel, you can also check out LinkedIn Learning’s vast video library for vetted and professional-looking tutorials. While the service’s $30/month subscription fee is nothing to sneeze at, you can binge-watch an unlimited amount of content and topics—making LinkedIn Learning a better deal than other on-demand online classes that come with annoying restrictions.
Skillcrush’s Free Coding Camp is our totally beginner-friendly intro to tech, techies, and kick-ass careers that you can complete in less than five minutes a day. Delivered straight to your inbox, you will learn how to code in the simplest terms possible—and even get to try writing your own code!—so you can see if learning coding is the right move for you…
Sometimes, it’s just easier to watch someone show you how it’s done. You can find all kinds of educational videos about nearly any coding-related topic nowadays: ex-Googlers sharing solutions on coding interviews, YouTubers livestreaming their coding marathons, and even programming veterans showing you how to troubleshoot a specific error in any language you want.
AGupieWare is an independent app developer that surveyed computer-science programs from some of the leading institutions in the U.S. It then created a similar curriculum based on the free courses offered by Stanford, MIT, Carnegie Mellon, Berkeley and Columbia. The program was then broken into 15 courses: three introductory classes, seven core classes and five electives.
This is our best piece of coding advice: If you can’t figure out why your code is broken, you can always look for solutions online. You’re probably not the first person to make your mistake, after all, and someone on the internet has surely already found a solution to your issue. Just “copy and paste” your error message into Google (or your preferred search engine), add a pair of quotation marks around the entire phrase so that you’re not just searching for keywords, then hit “Enter.” Hopefully, this little trick will lead you to the correct answer.
If you want to go pro and become a full-time developer, an intensive and in-person coding bootcamp might help you out, particularly if you learn best in a structured environment with real people to motivate you. However, these types of bootcamps are often the most expensive and time-intensive to attend: You’re looking at upwards of $15,000 for just the tuition, plus living expenses for a few months until you graduate.
Codewars adds some quirk to the proceedings by offering free coding classes with a martial arts theme. Solving specific coding “katas” (a term for training exercises in karate) will earn you ranks and honors as you move your way to becoming a bonafide coder. Who said learning to code online couldn’t be fun? Codewars also offers one of the more diverse lists of programming languages. Choose free coding classes on:
I can’t recommend Harvard’s CS50x Introduction to Computer Science enough. You can audit the course for free via edX and earn a certificate by completing all the assignments, or you can go at your own pace and watch all the lectures posted on Youtube. You can build your own DIY college-level computer science program with this selection of fifteen online courses (many of which are also listed in our Lifehacker U series).

The programming community is full of people who are willing to help the next generation of programmers. GitHub, the online hangout for developers who use Git to manage their coding projects, is designed for online collaboration. Not only do developers host and share their projects with their peers, they also provide code feedback and general advice to the community.

I think there’s so much stuff and challenges and quizzes and videos to help, but it gets really confusing sometimes when there’s so much information thrown at you. In the assignments tab I think you should add important key features, viewing the assignments from due earlier to due later, viewing assignments from highest level like 88% on a practice to 100% on a practice and separating them from videos and practices and everything else. It’s really a pain to scroll all the way to the bottom to see my assignments I didn’t complete since my teachers assign a LOT and I mean A LOT of homework on your app. I decided to rate your app fairly and not biased on we’re I like math or not, but rather the methods to teach and learn math. So there are some highlights. I like that you get hints for every single practice and it must be hard to make all of the detailed word problems. I also like that you can look back into the questions you messed up and learn from those questions.
This free online typing tutor was designed to help you learn to type as fast and easy as possible. Try a few lessons a day and you'll start to notice your fingers naturally move to the right keys. Even if it seems at times that you are making no improvement, keep on working at it and you will learn to type without looking! Remember to take breaks often though - its good for the body and for the learning!

By recreating existing projects, you’ll learn more about the inner workings of your highly customizable device. You might even find yourself inspired to create new ways to use your mini-computer and delve further into the world of code. (You can even enroll in UC Irvine’s The Raspberry Pi Platform and Python Programming for the Raspberry Pi Platform class through Coursera, if you want a little help getting started.)
A lot of people type with two fingers, and thus type around 10 - 15 words per minute. After completion of this course you should be able to type at least 45 words per minute, and even faster if you type often. If you at your job type nine hours a week you will be able to save the six out of these nine hours provided you triple your typing speed. That will be nearly 300 hours saved a year or seven weeks extra holy days a year. If you have 30 years left before you go on pension the course will save you about 230 weeks work. Are you self employed you will be able to stop working four years early. Or, if you could convert your increased typing speed into a pay raise, you could get four years extra payment before retirement. Learning how to touch type is probably one of the best educations you could invest in. And it won't cost you any money. You can here: calculate your own personal benefit from improving your typing speed. How ever it works out for you, you have probably never met a person who regretted spending some time improving his or her typing speed.
Luckily, institutions like the Flatiron School and The Grace Hopper Program offer scholarships or deferred tuition to make these bootcamps more affordable for under-represented groups like minorities and women in tech. Check out Course Report for a comprehensive breakdown of the many online and in-person bootcamps—including detailed reviews from their alums, which can help you decide whether a bootcamp is going to help you achieve your programming dreams.

If you want to better understand the relationship between hardware and software, then you’d enjoy the Piper Computer Kit 2, which has you building a Raspberry Pi-powered computer. Using this DIY laptop, you can learn to code through its custom Minecraft Story Mode challenges, use the drag-and-drop Blockly language to learn physical computing, or just pick up some basic Python from the pre-installed lessons.

It does not matter how fast you type if you have to go back and fix all your mistakes. Fixing mistakes takes more time than it does to just slow down and take the time you need to type accurately. Fast typing depends on developing precision muscle memory. Allowing yourself to type incorrectly will actually reinforce your bad habits and common mistakes! Slow your typing pace until you can attain 100% accuracy. If you come across a difficult word, slow down further to type it properly. Develop good habits and speed will be your reward.
