🔴 Why am I doing this course ?
As a course instructor at Atharvo - an edtech company, I instructed 100 students but faced payment issues. Making class videos public for students' access. Atharvo is fake, neglectful, and unethical company — avoid their courses. They fool students in the name of giving placement to everyone by charging 1000 rupees. Please report if you see this company running ads on social media
