Testimonials

What they are saying about us

Dear Pawel, These test were very good and they have helped me clear my Google PCA Certification. I took the test today March 28th 2023. I appreciate your effort in putting these question banks together. Totally recommended. Thanks Karan

Karan Bhavesar

Student

This is the best Python exercise course for beginner or experienced to brush up their Python knowledge. thanks, Pawel, keep doing good job.

Ramesh Kumar Singh

Student

Exactly what I needed. Most of the python course on Udemy start with the basics, which is tiresome over time... Courses like this on the other hand are designed to test your knwoledge gained in beginner courses. Recommended!

Tom Bonn

Student

A very good preparation course for an interview. The tasks are captious, so sometimes they require more time to solve them. This is an advantage of this course as it allows you to consolidate your knowledge :-)

Kopalnik

Student

I passed my developer certification after supplementing my studies with this course. Thanks, Pawel Krakowiak! Great resource to identify the gaps in your learning so you know what to review, with explanation why your answer was right/wrong and links to the docs.
