                            A virtual classroom platform is an e-learning technology solution that replicates — and often enhances — the physical classroom experience online. It enables instructors and learners to interact in real-time through video, audio, whiteboards, breakout discussions, polls, and shared resources.
                        </p>
                        <p class="text-soft text-base md:text-lg leading-relaxed">
                            Unlike basic video conferencing tools, dedicated virtual classrooms are built for pedagogy: attendance tracking, session recording, quizzes, LMS integration, and analytics that measure engagement. For tutors, training departments, and K-12 schools, a robust platform becomes the central hub for synchronous learning — eliminating geographical barriers and increasing retention.
