To focus during online classes, treat them like a real classroom: sit at a desk, keep your phone away, and actively participate instead of passively watching. Online classes are easy to drift through because no one is watching you, so the focus has to come from your own setup and habits.
Set up like a real class. Sit upright at a desk in a quiet, well-lit spot, not lying on your bed. Your environment tells your brain whether to focus or relax, so make it a study space.
Remove the biggest distraction. Keep your phone in another room or out of reach during class, it is the number one reason students drift off online. Close other tabs and apps on your device too.
Take notes by hand. Writing notes as you listen keeps your brain engaged and stops it wandering. Passive watching is where focus dies; active note-taking is where it survives.
Participate actively. Answer questions, type in the chat, ask doubts. The more you interact, the more present you stay, exactly like sitting in the front row of a classroom.
Example: A student in Coimbatore who kept zoning out in online classes started sitting at a desk, keeping her phone in another room, and writing notes by hand. She went from missing half the lecture to actually following it.
One practical tip: Use short breaks between classes to move, stretch, or rest your eyes, not to scroll your phone. Screen-on-screen breaks leave you more drained, while a real break keeps your focus fresh for the next class.
