How can you cheat to have more best answers?

You can create multiple accounts and vote for yourself, answer your own questions and pick them as best, etc. This is highly unethical, and a clear violation of the community guidelines, so I don't recommend it.

There are a couple things you can try to elevate your BA ratio.

1) review your answers, and vote for your answer for any Q that is in voting.

2) look for Qs with few answers. You can sort Qs by the number of answers to make this easier.

Cheating never got anyone any good ... in the end. Why would you want to do that?

Everyone learns from studying, doing their hw, research, getting wrong answers, and making corrections, even re-corrections, as many times as it will take for you to make it right. For some questions, though, when you begin to work, in real life, there are no quick fix answers, just responses.

Cheaters never prosper is a truism. For a time, they may succeed, but they will never make it for the long haul. Even if you get to live a long life, the feeling inside you will not allow you to experience a joy that supercedes all the money you have gained. Even if others cheat, doesn't mean you have to cheat.

You are not a clone of culture, or whatever your background, but it helps if you have mentors who are ethical and boundaried persons. I hope you get your priorities sorted out.

I don't think that there is a way to cheat. Just research and answer the questions to the best of your ability.

Cheating is not a good idea.Yahoo will find out about it and then your account will be gone.

The problem is although Y!A is slow, they will eventually find out about the ruse and deduct loads of points or terminate the account(s)

Arrange with friends to ask questions and pick you?

You go and vote for yourself for best answer.
