Frontend

Frontend practice

Choose a difficulty. Each level has five timed quizzes and a mock exam. Read the Frontend guide for topic context.

The Frontend track mixes HTML, CSS, JavaScript, browser APIs, performance, and accessibility — closer to a real general frontend exam. It is the best track for end-to-end readiness when you already have basics in each area.

What you will practice

Cross-cutting browser concepts: DOM, events, storage, fetch
JavaScript fundamentals used in UI work: arrays, async, closures
Accessibility and semantic structure decisions
Performance, assets, and common frontend tooling vocabulary
Practical scenarios that combine markup, style, and script

How to study this track

Use this track after you have warmed up on HTML, CSS, and React separately, or rotate it mid-week as mixed practice. Beginner covers foundations across the stack; Intermediate and Advanced add browser APIs, async flows, and scenario-style questions.
