College Tips & Tricks

Being a college student is probably one of the most expensive things you can do. Most of us here at Armor have had to experience this financial burden in some form or another, and know that finding even a penny to save can make all of the difference. We've gone ahead and compiled a repository of useful resources, textbook downloads, and other tools that might help make your college experience a little bit easier (and cheaper!) If you've got any other resources you would like to see added to this list, please feel free to contact us with the form below and we'll continue to build this list out.

Free Resources

When it comes to college courses, each one seems to "nickel-and-dime" us until we've got little to no money left for ourselves. The resources below are all free to use, and can supplement (or in some cases, replace) the paid resources you might have for your courses. Now, in being free resources, they aren't always up-to-date, and some of the material may be incorrect or misleading, but they are definitely worth taking a look at, and at least integrating them into your current learning process.


College Open Textbooks
College Open Textbooks is a non-profit that supplies open-source textbooks, targeted at K-12 and the first 2 years of college students. This resource has a ton of textbooks that might help with the subject of your choosing, but with the swell of college-written textbooks, you might not find the exact book you're looking for. A good resource for additional material.

Definitely a good one if you're taking extensive notes, or need to quickly find information from that textbook page.

Honorable Mentions / Paid Resources

Let's face it, free resources don't always capture the data that we're looking for. Not only that, but generally when the resource is free, it's update schedule is spotty at best and information can be misleading (or just plain outdated). Some of the resources below will require you to invest a little bit of money, but the return can definitely be worth it.


Diigo is an application that acts as an organizational tool for all of your documents, images, web pages, etc. It allows you to highlight and save snippets right from different websites, upload images, highlight and makes notes on documents, and a ton of other functions. If organization is an issue for you, Diigo might be the tool for you. Running at $40/year, this tool ends up being less than $4/month, and is one you should have on your radar.


Amazon Prime: Student
Amazon Prime has become an integral part of how we operate here at Armor. Nothing beats ordering a part or product, and it being on our doorstep no more than 2 business days later. This same service is available at a discount for students, and is something we believe is worth looking into. This will save a ton of headache when you need a specific product for a project you're working on, or if you forgot to order you textbooks on time. Amazon Prime is our recommended paid product for this list.

All of these resources should help to round out and complete your college learning experience. If you've got any suggestions for this list, please fill out the form below and we'll make sure to evaluate and add links as we can!
