<p>I didn't realize that I needed academic teachers until two weeks ago and I already have 3 recs (2 non academic, 1 academic).</p>
<p>Yes, 4 recs are too many, but you have to have the 2 academic. If they have already been sent then there is nothing you can do. If not, then just send the required teacher recs and one more- only if really adds something to your application.</p>
