This course delivers 600 carefully-crafted, scenario-based multiple-choice questions covering the entire full-stack web development landscape — from frontend fundamentals through advanced production architecture.

Organized into six 100-question practice tests, you'll work through:

• Test 1: Frontend Fundamentals & React — the Virtual DOM, hooks, Context API, closures, the event loop, and CSS layout

• Test 2: Backend & Node.js/Express — the event loop, middleware, authentication, GraphQL, WebSockets, and background jobs

• Test 3: MongoDB & Database Design — embedding vs. referencing, indexing, aggregation, replica sets, sharding, and multi-tenancy

• Test 4: Full-Stack Integration & APIs — API contracts, caching, optimistic updates, real-time features, and Sagas

• Test 5: Testing, DevOps & Deployment — CI/CD, Docker, Kubernetes, blue-green and canary deployments, observability

• Test 6: Advanced Patterns & Best Practices — micro-frontends, CQRS, circuit breakers, resilience patterns, and distributed transactions

Every question comes with a detailed explanation for all four options — not just the correct one — so you understand exactly why an answer is right and why the alternatives fall short. Questions are deliberately written to connect concepts across tests and reinforce genuine, applied reasoning rather than rote memorization.

This course is ideal for interview preparation, self-assessment, and reinforcing what you've learned from other full-stack courses or real project experience. Whether you're a student consolidating your knowledge or a working developer sharpening your judgment before a technical interview, these practice tests are built to help you think like an engineer — not just recall a definition.
