Stack Exchange – a collection of question-and-answer communities. If you’ve got questions about chemistry, math, programming, or pretty much anything else, you’ll probably find an answer here.
Wolfram Alpha – a “computational knowledge engine”, this site can calculate basically any math problem and come up with data on all kinds of things! Step-by-step solutions to math problems used to be free, but they cost money now. For a free (but less easy-to-use) solution, try SymPy Gamma.
StudentRate – a site that aggregates student deals and discounts on clothes, travel, textbooks, electronics, and lots of other things.
Sleepyti.me – uses the sciences of REM cycles to calculate the optimal time you should go to bed in order to feel well-rested, based on when you plan to wake up.
Habitica – formerly HabitRPG, this website is a great tool for helping you develop better habits, and breaking bad ones!
Todoist – task manager of choice. This website has a clean design, great organizational features, and your tasks sync across multiple platforms.
Google Calendar – old and trusty. Google Calendar hasn’t changed a whole lot in the last few years, but it really doesn’t need to. It is accessible in any browser, has great smartphone apps, and just works.
Dropbox – Dropbox keeps all your files synced, updated, and backed up across all your computers. Recently, their browser interface has gotten much better – you can now preview most file types right in the browser without having to download them.
Lynda – a huge library of video courses that can help you learn tons of skills, mainly centered around computing and media production. Lynda is particularly good for learning the ins and outs of computer software.
Mint – a tool that lets you view all your financial account in one place, track your spending, and set up budgets.
Rate My Professors – a site that allows students to write reviews of professors. Don’t take this sites ratings as the golden standard, but it can be incredibly helpful within reason.
Coggle – a cool little mind mapping tool that lives in your browser.
Your college website! – If you’re not familiar with it, get on it. Most college websites have course catalogues, schedule planners, financial aid information, scholarship listings, academic calendars, student job boards, and other useful things.
Written Kitten – potentially the greatest writing aid ever invented. Set a target word count, and whenever you hit it, you’ll get a new picture of a cat. What could be better?
Cheatography – a really cool site that collects cheat sheets that condense information on all kinds of topics. This could be helpful for building study guides.
Bibme – a tool that can help you automatically generate bibliographies and source citations. This website lets you search for books and other sources; if it recognizes what you searched for, it can often auto-fill all the citation fields. (Not all citation generators do this)!
Ankiweb – This site is legit because it’ll let you create and study your flashcards in the browser. However, you do need to have Anki downloaded first.
Instructables – a site where people can post DIY project tutorials. You never know what you might find!
