Help with these Math questions

<p>Yeah, I don't know, I don't plan and conjecture anymore. It is really taunting. I just go for it with an empty mind.</p>

<p>My best friend is a genius in Math, he is taking topology in a University Course Online and he said that when he gets 2400, he did not seek after grade. He just loves to solve Math problem and he said to himself that no matter what happens, Math is still so attractive. So he solved like 4 practise tests everyday without timing. He kept doing so from the beginning of senior to the test. And yeh, so I am trying to circumvent myself.</p>
