The conversation between human and AI assistant.
Where can I find good viva questions for physics and chemistry (class 12) for free?
No, I haven't. How do I know which website will have the best questions?
It's hard to say which website has the best questions, but all three websites I mentioned have good reputations and are frequently used by students. You may want to try browsing through each website and seeing which one has the most relevant questions for your needs.
