Qvault’s Big O Algorithms Course

Big O Algorithms Course Qvault

Learn Big O Algorithms

Learn by doing — A mix of multiple-choice questions and writing code to tackle each lesson’s coding challenge makes for faster learning than you would with videos.

Free tier — Free basic access to all lessons forever. We’ll even hook you up with Pro features on a 7-day free trial.

Learn Big O with Go — Go is one of the top paid and fastest-growing programming languages. Improve your Go skills while increasing your understanding of algorithmic complexity will make you a faster and more employable programmer.

Why should you learn Big O Algorithms?

big o algorithms course 1024x576 1

Big O is the most important topic in algorithms, and will make your algorithms faster, leaner, and better.

Whether you need to brush up on your big O skills for a coding interview or to take on a project at work, or need to test your own algorithms for efficiency or complexity, our big O course teaches you everything you need to know about big O, as you code in Go and complete our coding lessons and multiple-choice questions.

Stack Overflow’s 2020 report on Go:

$140,000 average salary — 2nd highest paid language (in the USA)

Growing in popularity — and 3rd top language coders are looking to learn

Loved by coders — 5th most loved language, up from 10th the previous year

We love Go because it is:

Simple & quick to learn — Go is intuitive, clean and easy to read, and has a small syntax

Concurrent — Easy to do multiple things at once with Go without running into bugs or slowing you down

Very attractive to employers — Google and many other large companies are hiring Go developers

Still not sold on Go? Check out all 7 reasons why you should learn Go this year.

Frequently Asked Questions

Interested in upgrading to get full access to our Big O Algorithms course, but unsure what that entails?

What’s the difference between Basic and Pro?

A Basic account is, well, basic. You can demo Pro features on the first 6 exercises of each course (such as our Big O Algorithms course). But after that, if you’re on a Basic plan, you’ll only be able to read the course material and play in the code sandbox. You won’t get access to feedback on your code know if you got the right answers.

Qvault Pro has everything in Basic, plus all the advanced tools, content, solutions, and certifications that you need to make your learning faster.

A Pro account lets you practice much more efficiently by getting instant verification of all your code solutions. If you get stuck, you can use the “cheat” feature to take a look at the solution and quickly see what’s holding you up.

Additionally, one of the biggest benefits our Pro subscribers get is access to free certificates of completion when they finish a course. Showing off your work to employers is a quick way to get that high-paying tech job

For a full list of the differences between Pro and Basic, view our Pricing page.

Do you offer any discounts?

Our top priority is improving the courses, the app, and your experience — so your feedback is super valuable to us.

If you’re happy to help us keep improving our courses to be the best they can be, we’re currently offering a 25% discount to anyone who completes this feedback form. When you’re finished with the survey you’ll be given a coupon code!

Do I need to know how to code in Go or about Big O Notation and Algorithms before signing up?

Our Big O Algorithms course was designed for users to complete lessons coding in Go.

The course starts from the basics of what an algorithm is, how logarithms work, as well as explaining the basics of big O notation. So even beginners should be able to complete the course and move on to the more challenging aspects once they understand these basics.

If you want to learn how to code in Go first, we recommend you first take our Go Mastery courses.

Why should I upgrade to Qvault Pro?

I built Qvault based on the lessons I’ve been learning as a technical hiring manager, so everything we do here is designed to take you from your current level, and get you an eventual high-paying programming job. If you’re ready to accelerate your learning and apply your skills to real-world scenarios, then Qvault Pro is for you.

Aside from the direct benefits, if you like what we’re building here at Qvault, your support helps us improve the platform.

How easy is it to cancel my subscription if I don’t like it?

We do our best to be transparent about pricing, and never want anyone keeping a subscription they don’t use. You can cancel your subscription any time from your settings page and you won’t be billed again.
