Hi Candidate,

Web Sessions and Online Lectures are the most common modes of Education these days, and mainly because of the Covid Pandemic people have to use it as the only way for communicating with experts and teachers.

You can book Doubt Clearing sessions with several Digital Platforms such as UnAcademy, CourseEra, Doubt Nut, and others too. You can avail their Free Trial courses to select the best as per your convenience.

Hope that this answer was helpful for you.
