Told you so didn't get through even one yet.
No isssues about that, that's just one thing. There are hundreds of others which are studied now by "science" but are already explored in our culture. Now you know why I say our culture was the best. Others' are just stories.

I have not read any religious book yet. But I have more plans regarding that. And to prove how Hinduism is not just belief, I can give one example and one is enough. Ever heard that "suryadev" travels in 7 "raths" ? Ask from your parents about it. And some "modern" and brainless people will say its mythology, fiction etc etc. But neither of them cannot understand that this relates to seven colours of sunlight (VIBGYOR). Some foolish people also call it "accident" but I don't care. I know our religion is not like theirs.

Its not an experiment. Its a way of making money. CBT earns a lot of profit than omr. But those fools do not realize their failure of exam conduct has costed more than a offline examination. Spam on twitter #CUETofflinetest maybe they hear. Ask your friends or who ever you know for it.

I also think offline would have been a better option .Recently all exams that were conducted was offline and there was no problem .So what was the point of conducting cuet online . I think NTA is doing all of their experiments on us ...

Raj Singh 2 weeks, 2 days ago

By using the method of friction, positive charge is developed on one of the bodies and negative charge on the other. When these two bodies are brought close, they attract. Some objects have tendency to gain positive charge (example glass and ebonite rod) while some objects have the tendency to gain negative charge(example silk).
