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.
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.
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).
If you want to learn how to code, taking your first steps into this huge universe might seem like a daunting, if not intimidating task. Here’s the big secret: There are plenty of free (and inexpensive) resources you can use to give yourself all the help you need, teach yourself new techniques, and make this learning process fun and exciting—as exciting as coding can get, at least.

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.

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.

Touch typing is the ability to use muscle memory to find keys fast, without using the sense of sight, and with all the available fingers, just like piano players do. It significantly improves typing speed and eliminates errors. Touch typing simply makes you more productive and it is a skill worth learning. However, many people engage in the bad habit of ‘hunt-and-peck’ typing, even those seasoned professionals with years and decades of computer experience. It  is easy to understand, though, as touch typing requires dedicated practice to  learn it well.


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.

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.


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.
Spend an afternoon brushing up on statistics. Discover how the Krebs cycle works. Learn about the fundamentals of music notation. Get a head start on next semester's geometry fundamentals. Prepare for the SAT, GMAT, LSAT, MCAT, NCLEX-RN, and AP exams. Or, if you're feeling particularly adventurous, learn how fire-stick farming changes the landscape of Australia.

Created in 2006 by educator Salman Khan, Khan Academy is one of the original free online-learning institutions. With step-by-step video tutorials, you can  learn how to program drawings, animations and games using JavaScript and ProcessingJS, or learn how to create webpages with HTML and CSS. See, especially, Khan's "Hour of Code," designed to introduce students to one hour of computer science and computer programming.

As a self-taught programmer, you might also benefit from books that offer broader advice on the profession. You’ll improve your thinking and habits, traits you can apply to any language you decide to learn. Steve McConnell’s 900-page Code Complete: A Practical Handbook of Software Construction (2nd Edition) is considered the definitive guide for best practices, with data-backed advice on everything from project design to debugging code.


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 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.
