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 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).
Take a few minutes (or a day) to think about the reasons—the real reasons—why you want to learn a programming language. Be honest with yourself. Are you trying to learn the barest minimum to score a promotion? Are you looking to make a big career change? Do you want to create the next greatest app? Thrill your roommates by programming your various smart devices to do something awesome?
I'm Dave Henderson! For over 34 years, I've made a wonderful living for myself and family of four creating world-class water features using real and faux rock in sunny San Diego as well as professional sand sculptures all around the world. And now I'm taking what I've learned about starting successful businesses, contracting, sculpture, water feature construction, and more, and sharing it with the world. It's my mission to help people like you enjoy more success both in your business and in your personal life.
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.
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.

No matter how many certificates and coding workshops you complete, or how many programming languages you learn, the proof of your coding skills will be in your programming project. While your personal project doesn’t have to be as ambitious as creating the next Google Maps, it should be something you’d want to work on 24/7 to constantly improve and expand its scope.
Third, Keybr.com lets you introduce as few keys as possible to the lesson, adding more keys automatically when it decides that you are proficient at the current level. When you only start learning it generates lessons with words from a very small alphabet of the most frequent letters. When your typing speed for every key in that alphabet reaches certain threshold, the algorithm adds the next most frequent letter to the alphabet. And so on, until the next letter. This way you will learn the most frequent letters first, and the least frequent ones later.
What an incredible app. I’m so impressed. This company deserves loads of money to be thrown at it for making it free. My son has just switched from a Cambridge school to an American School and missed a lot of work. I think we were both about to give up. I didn’t know where to start to help him and being his new school is completely iPad based we felt deep despair at just the thought of trying to navigate through classrooms codes and half working text book apps. Now it’s all here in one place! Simple well explained and the practice really gets your confidence going. He had some maths homework and instead of the total melt down we both would have had trying to work out what was going on we flew through it!! THANK YOU! I love the fact that all the grades are here too so if there is a concept he is struggling with we can go back in the grades to see where that was introduced and work through it! We have been struggling for months trying to find the answer on line. It was only due to the fact that Khan kept coming up that I googled it and found the app. I truly pray this company gets loads of financial support to keep this app going! THANK YOU THANK YOU THANK YOU!!
That's a great list, Kevin. However, nearly all above-mentioned course/tutorial providers provide content for nearly all programming languages/frameworks. Hence a newbie learner would be confused which learning platform to choose out of the lot. For ex. if one is interested in learning Python, all the above-mentioned platforms provide Python courses/tutorials. To solve this dilemma, Hackr.io (https://hackr.io) is the programming community where learners can find the best online programming courses and tutorials recommended by the community. PS: Sorry for the self-promotion ( Am Hackr co-founder) but I thought of informing the readers about the possible solution.

The typing lessons of TypeLift are not just static content. Every time you start a typing practice the lessons are assembled dynamically to increase your learning effect and to avoid memorizing frequently practiced exercises. On top of that our smart error analysis repeats frequent mistakes while you practice to make your individual training even more efficient.
Instead, Keybr.com generates random, but readable and pronounceable words using the phonetic rules of your native language. These words look almost natural, and often they really are. Typing sensible text is much easier than repeating random letters, and it helps you to remember frequent key combinations. The latest point is very important. For example, it’s almost impossible for the letter ‘W’ to follow the ‘Z’ in English, and you will never type this combination in Keybr.com. Instead, you will type more common words, such as «the,» «that,» «with,» and so on. And soon you will learn how to type the «th» combo really fast.
Your answer can help determine which programming language(s) you should master, as well as what sort of commitment (in time and money) your goal may require. For example, if your dream is to create the next great operating system or a killer alternative to PhotoShop , you would benefit from a formal computer science education that teaches you C++, as well as more complex topics like data structure, algorithms and memory allocation.
Whether you’re an adult looking to transition into the tech industry, a student looking to learn the latest language, or a hobbyist who just wants to understand how software and services work, all you need is a computer and internet access to start your programming journey. But before you take a flying leap into The Matrix, here are our best tips and resources to set you off on the right foot.

The less work your fingers do to press the keys the faster you will be able to move them. Most keyboards require only a light touch to register a key stroke, so there is no need to mash the keys down. You should type with the minimum force necessary. You will type faster and put less strain on your body. Typing involves muscles not only in your fingers, but in your hands, arms, back, shoulders, neck and head.
The free typing lessons supply the complete "How to type" package. Animated keyboard layout and the typing tutor graphic hands are used to correct mis-typing by showing the right way to type for your learning and practice experience. Lessons' difficulty gradually raises as it starts from only 2 characters and ends with the entire keyboard. When the lesson ends, you can learn a lot from the practice trends: WPM, accuracy and errors distribution.

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.
JUST RELEASED! "Makin' Rocks" covers everything I've leaned after 34 years of hard work and experience making a living building things with my hands. I teach people like you how to create the same amazing water features as a master sculptor like myself! With tons of pictures and hand drawn illustrations from decades of work you will see actual project examples of how things get done. And even how to set up your own faux rock contracting business selling $10,000, $15,000 and $20,000 or more projects! Get this book and get in the game! 

Start small, but think big. Your project should involve skills you currently have in your toolbox, but you should also have a plan for future features and skills you’d need to turn that vision into reality. Without applying your coding skills in a few projects, you wouldn’t even be considered for professional coding gigs—so start planning and practicing. (Our advice? Use your coding chops to build an amazing setup for game night.)

It is more important to have a low error percentage than a higher speed. The low error percentage will be your best guarantee for success in the following lessons. You can follow your progress at the statistics page (just press the button 'Statistics' at the upper right corner) You should strive to do all lessons flawless (or at least with max two percent error) before you go on to the next lesson. If you learn to type flawless a high typing speed will automatically ensue. By the way, the error statistics will only save your best results.
Do you have a smarthome device like the Amazon Echo? You can put your coding skills to the test by creating customized mini-programs to get more functionality out of your devices’ digital assistants. Amazon’s Alexa may already know many basic voice-command “skills,” like reading the latest news headlines, but you can teach her more complicated tasks by coding in Node.js, Java, Python, C#, or Go. (Or, if you want to start with something easier, try the simpler Alexa skill blueprints site.)
If you don’t know how to touch type, this is where you need to start. Having the ability to type without looking at the keyboard is the most important factor in achieving a fast typing speed. Even if you have memorized many of the keys, unfamiliar keys will slow you down just like speed bumps on the freeway. Taking your eyes off the screen to peek at the keyboard disrupts your focus and costs you time. You want to be able to keep your eyes on the screen and your fingers moving to the correct keys without thinking. Achieving this kind of flow takes practice. The better you can do it, the faster you will be. Read on to learn how.
My name is Jamie Spencer and I have spent the past 5 years building money making blogs. After growing tired of the 9-5, commuting and never seeing my family I decided that I wanted to make some changes and launched my first blog. Since then I have launched lots of successful niche blogs and after selling my survivalist blog I decided to teach other people how to do the same.
