Google makes our internet-connected world go around. There's Android on your phone, Google Maps for navigation, Gmail for email, YouTube for videos, Google Home for smart homes... and let's face it, Google itself is the gateway to the web.

So, you need to know Google and its products well if you want to embrace the century of technology. It's best to take a short course that gets you acquainted with the apps, especially if you're a beginner. Otherwise, having a cheat sheet might help. Either way, you will be well equipped to handle anything that Google throws at you.

1. G Suite Training (Web, Chrome): Official Tutorials for Google Apps

The best thing to start with is Google's own official "learning center". This includes a variety of Google Apps, like Docs, Sheets, Slides, Drive, Gmail, Calendar, Google+, and more. At the website, you'll get step-by-step instructions on how to use any service.

The better option is the G Suite Training extension for Chrome. It's completely interactive, so as you use the app on a regular basis, it will teach you tips and tricks. In short, much like KeyRocket for Gmail teaches keyboard shortcuts, the G Suite Training extension will make you a better Google user.

Finally, check out the G Suite Training videos page to watch instructional videos about every Google app. And yeah, if you don't use Chrome, remember, you can install Chrome extensions on Opera or other Chromium browsers.

4. Android 6.0 Quick Start Guide (Ebook): Official Tutorial

By now, you should have ideally got Android 6.0 Marshmallow on your phone or tablet. It's a fantastic operating system, but if you're new to Android, you need to know a few things. Even if you aren't new, there are awesome Marshmallow features to check out.

Google released this official ebook on Google Play Books, its ebook store, which you can download and read for free on any device. It's a complete beginner's guide, introducing you to the basics of Android and everything you need to know to use it.

In case you haven't yet got Marshmallow as an update on your phone, you should probably install a custom ROM based on Marshmallow.

5. OK Google Commands (Web): All the Voice Commands for Google Devices

If you have an Android phone or tablet, a Chromebook, or a Google Home smart device, you need to start using voice commands. Google has arguably the best voice recognition system, and customized its devices to perform actions by just talking to them.

And while we've listed 20+ useful OK Google voice commands, there are far too many other commands to keep track of. That's why the new OK-Google.io site is so useful. It lists all the commands available, and neatly sorts them in categories. Click a category and you'll see all the things you can say to Google devices with it.

We've already said that every Android user needs to use OK Google, but this site will show you how it's useful on Chrome OS and other gadgets too.

Which Google Product Is Most Confusing?

Google prides itself on its simplicity, but a lot of users still find many of its products complex.

Which is the most confusing product, according to you? Is it something like Google Home that uses only voice commands, or an operating system like Android, or a single app like Gmail?
