<p>I say talk to your teacher. Just tell them, like on the first day, that you are on the shy side, but you will try and participate. That way, they will understand your situation and call on you more than others in place of you just raising your hand , calling out, or whatever. I think if this is that big of a problem, just talk; most teachers will understand and appreciate your boldness and maturity.</p>
<p>Well, having a 4.0(pride is a horrible thing :(), I say to ace the tests, as said before. They are your ticket to an A. The homework is not as importent, but still needs to be done because it leads to good test grades. Also, I know this sound cliche, but study. Not only will it get you good grades, but it will prep you for college, which is all about studing to pass the tests.</p>
