ExamPractice

Education / test preparation

Client problem

Students needed a fast, mobile-friendly way to practice exams, track progress, and revise weak topics with a clean, distraction-free UI.

Solution

We built a Next.js-based practice platform with organized question sets, timed practice flows, and progress tracking to support consistent preparation.

What we built

  • Topic-wise question sets with filters
  • Timed practice mode and review
  • Progress tracking and performance summary
  • Bookmarks / saved questions
  • Admin-ready structure for adding new tests

Key modules

  • Questions: sets, difficulty, tagging
  • Practice: timer, attempt history, review
  • Progress: topic performance and summaries
  • Saved: bookmarks and quick revision
  • Admin: add/edit question sets (extensible)

How it was built

  1. Designed a clear information hierarchy so students can find tests quickly.
  2. Built reusable UI components for question rendering and navigation.
  3. Focused on performance so switching questions stays instant.
  4. Kept the structure extensible for new exams, topics, and features.

Challenges

  • Keeping the UI minimal while still supporting review and tracking.
  • Making the practice flow smooth on mobile devices.
  • Designing a structure that scales with more questions and tests.

Quality & release

  • Manual QA of practice flows (timer, review, navigation).
  • Basic performance checks for smooth mobile interaction.
  • Release checklist to ensure content and UI remain consistent.

Architecture

  • Next.js app structured around reusable modules and clean routing.
  • Clear separation between UI presentation and practice flow logic.
  • Data model designed to scale with more tests and topics.

Key decisions

  • Kept UI minimal to reduce distraction and improve completion.
  • Reusable components so new exams can be added quickly.
  • Mobile-first layouts to make practice comfortable on small screens.

Scalability considerations

  • Ready to add more question banks and exams without rewriting UI.
  • Supports growth in content with consistent tagging and filtering.
  • Designed for incremental additions (leaderboards, subscriptions, analytics).

Outcome

  • Smooth practice experience on mobile
  • Clear progress visibility
  • Faster revision loops

Stack rationale

  • Next.js for fast routing and a production-ready structure.
  • TypeScript for safer iteration as the platform expands.
  • Component-driven UI so new content can be added without rewrites.
