<p>Does senior year matters, as long as i don't have Cs and Ds?</p>
<p>My counselor says first semester matters especially if its a top tier school. However, it won't hurt if you get a few B's, even a C, on lower tier schools. Even for top tier schools a B or two won't hurt.</p>
<p>Most people seem to say that as long as you're still taking the hardest course load and doing well first semester (one B or something with 3 strong years behind you won't hurt), you should be fine at top tier schools.</p>
<p>Other than for EA or ED schools, your first semester grades are just as important as junior year. (Many EA and ED schools will want to see your first mid-marking period grades from senior year.) Second semester is not as important, unless your grades tank (in which event your acceptance may be revoked).</p>
