Sit this when you can do these without looking them up
This is not a certificate of attendance. It is 60 questions in 140 minutes at 70% with no partial credit and one attempt, and roughly a third of the paper is foundations — the certificate is for the whole language, not the parts you enjoyed.
- Explain what alt text is for, and write one that would actually help someone using a screen reader
- Say which HTML element is right for a given piece of content — nav vs div, article vs section — and justify it
- Predict which of two conflicting CSS rules wins, using specificity and source order
- Draw the box model for a given box-sizing value, and say what margin collapsing does to two stacked paragraphs
- Build a header bar with flexbox and a page layout with grid, without checking a reference
- Write a media query that reflows a layout at a real breakpoint, and say why mobile-first changes which direction it points
- Debug a flex child that won't shrink below its content width, or an absolutely positioned element that ignores its intended parent
If several of those are unfamiliar, the course below is free and covers all of it. If you would rather find out than guess, there is a practice paper at the same level — ten questions, marked as you go, no account, nothing recorded.

Every paper is drawn to this mix, so the weights are a promise rather than a guide. The numbers are how many of the 60 questions come from each area.
- 4
Document structure and the browser
Doctype and standards mode, the head/body split, meta charset and viewport, and what HTML, CSS and JS each do.
- 3
Text, headings and lists
Heading hierarchy, paragraphs, emphasis versus styling, and ordered, unordered and description lists.
- 4
Links, images and media
Anchor paths and targets, rel=noopener, alt text, intrinsic width/height and layout shift, figure/figcaption, audio and video.
- 4
Semantic HTML and tables
Landmark elements and their implicit ARIA roles, article versus section, and accessible tables with scope.

Labels and association, input types, button type defaults, and built-in validation attributes.

Accessibility fundamentals
Contrast ratios, keyboard focus, tabindex, skip links, and when ARIA is and isn't appropriate.

The box model and sizing units
Content/padding/border/margin, box-sizing, margin collapsing, and px versus em versus rem versus viewport units.

Everything on this syllabus is taught free
The HTML & CSS course covers the whole syllabus above across 32 lessons, with a playground in each one. Work through it first — the exam is the same material under a clock.
Open the HTML & CSS courseWhat sitting it is like
The exam opens full screen with a countdown, a question at a time, and a grid showing what you have answered and what you have flagged to come back to. Nothing is submitted until you say so, or the clock reaches zero.
Every answer saves to the server as you give it. If your laptop dies at question forty, sign back in and you will find question forty exactly as you left it — with however much time was left still ticking, because the clock does not pause.
Leaving full screen or switching tabs is noted but does not end your exam. It is a record, not a trap: nobody is auto-failed for a notification stealing focus.
When it ends you get your mark, a topic-by-topic breakdown, and every question with the right answer and an explanation — whether you passed or not. Passing also produces a certificate with a link anyone can verify.
