Educational Platform for BCS Candidates

Vertex for BCS is a preparation platform for BCS candidates in Bangladesh, and it leads on structured, expert-led learning. I first built it on a MERN stack — MongoDB, Express, React and Node — and later rebuilt it on Next.js with a NestJS backend over PostgreSQL, which is what runs today.

The site is arranged around a study cycle rather than a brochure. Chapter-wise lessons sit inside a course catalogue, timed mock quizzes run in real time, and progress tracking shows a candidate what they have already covered. That only works for a signed-in student, so authentication is part of the build rather than bolted on: register and log in gate the study side, while courses, pricing, gallery, FAQ, about and contact stay public for anyone still deciding.

The quiz engine is the centre of the build: timed mock tests that run against the clock, with each attempt feeding the progress view a candidate checks between sessions.
