<p>"...you should use a teacher from junior year, or a current teacher if they have known you long enough to form an opinion. It is best not to go back too far, as colleges want current perspectives on their potential candidates. All the better if you get a recommendation from a teacher who's also been involved with you outside the classroom, but unless a college specifically requests it, don't use a coach or someone who can't speak to your academic achievements and potential."</p>

<p>In other words, ask whoever knows you better and would write you the better letter.</p>
<p>I was convinced my math teacher hated my guts. When he wrote me a rec for a summer program, I could not believe how good it was. It said that I am one of his best students, very mature, etc etc. It surprised me because I never really do anything during class (even though I get high 90s in his class, which is considered the most difficult in my school). He always tells it like it is, he wouldn't lie about me on the rec.</p>
<p>You never know. Unless you are ABSOLUTELY SURE your teachers hate your guts, suck it up go for it.</p>
<p>I asked my freshman/sophomore teacher cause I had him for two years and he really liked me. It really doesn't matter when the teacher taught you as long as he/she knows you well.</p>
<p>How do you tell for sure whether or not a teacher likes you?</p>
