Overall, the design looks very nice to me and I like the consistency of the elements. I would check the legibility and contrast of some of the text. One little thing that I find confusing in consistency, why is the "quiz finish" red?

I would focus on improving the content, you talk about coding but the menu includes photoshop, ui, ux etc.

I like the idea of a quiz where you set the right benchmark for the user. 

I like your approach of immediately engaging users by asking what they came to learn and using simple questions to gauge their level. The illustrations are also a great touch - they're relevant and really capture the brand personality of the app. I'm a fan of the brutalism style you've chosen overall.

However, there are some areas for improvement. The copy could use some polishing as there are inconsistencies and confusing words. More importantly, your perspective and design rationale are missing, which leaves the work feeling like just a collection of images. It would be great to understand why you chose this particular onboarding approach.
