"I liked the pace and amount of detail provided. It was perfect for me. There's a ton of information packed into these videos. I would pause the videos often so that I could keep up, but there's nothing wrong with that. It was a good pace."

"I was a little uncomfortable spending money on this course, but it was totally worth it. The whole experience is great, and it's better than other courses I've taken. The assignments and the code reviews are awesome! They force your mind to remember the concepts for longer periods of time, using active recall. The explanations are clear, the course is split into different concepts, and there's code underneath every lesson, which is very useful. I've learned a lot."

Leonardo Favale (Student)


Burning Questions Asked

How much does it cost?

The early-access price for the course is $147. But the final price, when the content is all done, will go up to $399, and there will be no more discounts going forward.

So if you want to get in at the lowest price it will ever be at, do it now.

How do I know it's for me?

This Ruby on Rails course is for you if you know a little bit about Ruby, or a similar language (e.g. Python, Javascript), but you've never used Ruby on Rails before.

That's because it doesn't assume any Rails-related knowledge on your part.

Is the course content-complete?

There's about 90% of it done (over 8 hours), and we're adding new lessons every week.

The benefit of joining now, is you get more access to your instructor via email and the private community forum than you would after the early-access ends.

How much do I have to participate?

It's totally up to you. But don't enroll in this course if you're not serious about leveling up your career.

If that's not you, don't buy it. You won't hurt our feelings.

When can I get started?

Right away! Even though the course is not content-complete yet, there are enough lessons already done (more than 8 hours of video) so you can start learning right away. With more lessons being added every week.

Does my location matter?

No. You can learn from anywhere, at any time. And you can ask questions via email, or in the course's community section. In your own timezone.

What kind of projects will I be working on?

There are three types of challenges available in the course: code examples, assignments, and complex projects with code reviews.

Projects will be used to test your skills, and you can submit your code to be reviewed by your instructor.

What if I don't like it?

We totally understand no course can meet everyone's expectations, and that's why we're offering a 7-day money-back guarantee.

If for some reason you don't like it, just send us an email and you'll get all your money back. No questions asked.

Why would I need 1:1 mentoring?

If you want to learn how to build a SaaS product quickly with 1:1 help, in-depth code reviews, and a clear roadmap, then the mentoring package is for you.

You get 1-2h-long live video calls where we go over your assignment for the week and we discuss your progress.

What if I already know Rails 6 (or an older version)?

There are new features in Rails 7 that are pretty significant (eg. Hotwire, and the new asset pipeline).

And all the practical examples, and projects in the course use these new features.

What if I have more questions?

For any questions, please send an email over at office@mixandgo.com. We normally reply in less than 24h.

How do I know where I left off?

The content is more like an online class, it's not just videos. It's also quizzes, assignments, and code reviews.

Reporting on your progress is also available. That's how you can quickly track progress.
