Go practice: free questions and flashcards for Go 1.26
A free course in the Go programming language: multiple-choice questions and flashcards on the language, generics, concurrency, errors, the standard library, the runtime, performance, testing, tooling and idioms, written for Go 1.26.
A question gives you a short program: predict what it prints, find the deadlock or pick the right API. The explanation after your answer says why, with the specification or the standard library documentation behind it. Every code snippet was compiled and run against Go 1.26.

What you practise
The course follows the language as the specification defines it and the standard library as its documentation describes it: the language and generics, concurrency, errors, the standard library, the runtime, performance, testing, tooling and idioms — from slices and maps to the scheduler and the garbage collector.
Most questions are small programs. You read the code, choose one of four options and then read why, with a link to the documentation the answer rests on. The flashcards cover the same ground as short concept cards.
How the course works
Pick a set — each is one topic, such as slice headers, unbuffered channels or wrapping errors with %w — answer its questions and read the explanation after each. The flashcards work the same way, a set to a topic, such as zero values and nil behaviours.
What you can do:
quizzes on question sets, by area — 30 sets need no account
flashcards on the same topics, in sets of their own

Your goal: Go 1.26
There is no Go certification to sit: the Go project runs none, and this course is not connected to it. The goal here is the Go 1.26 exam in wspell — our own questions and flashcards on the language and its standard library. The facts below come from our Go guide.

frequently asked questions
Is the Go course free?
Yes. All 384 sets are free: 30 need no account at all, and a free account opens the other 354.
Which version of Go does it cover?
Go 1.26. Every code snippet was compiled and run against a Go 1.26 release, and the explanations quote the specification and the standard library documentation. Go 1.27, released in August 2026, is not covered yet.
Is there a Go certification exam?
No. The Go project does not run one, and wspell is independent of any exam provider. This is our own practice course, written from the Go documentation.
How is it different from A Tour of Go?
The tour teaches you the language, lesson by lesson. This course tests it: short programs where you predict the output, find the deadlock or pick the right API, each followed by an explanation of why. Take the tour first if Go is new to you.
What does a free account add?
The other 354 sets, and your results saved to your account rather than to one browser, so they follow you to any device you sign in on. Results you earned here without an account are saved to it when you sign up in the same browser.
Who writes the questions?
They were written for wspell from the Go specification and the standard library documentation, and each answer links the documentation behind it. wspell is not affiliated with Google or the Go project.
Can I use it on a phone?
Yes. It runs in the browser on a phone or a computer, and the code in the questions wraps to fit a small screen.
