You can find the Reviews section on our website. Here you can leave your feedback and read the opinions of other users.
You can also search for reviews on the Internet. Type "CodeGym reviews" in Google and you'll get quite a few results. We do not filter out third-party reviews, so you can not only see positive reviews (of which there are many more, which is pleasing), but also constructive and not very constructive criticism.
PS: Reviews are subjective, so you can only form your own opinion once you try something yourself. Try level 0 on CodeGym - it's totally free.
