Teacher recommendations

<p>Pomona prefers recommendations to come from junior or senior teachers. However, they will accept recs from sophomore grade teachers. How bad does it look if the only recs one gets is from sophomore teachers? The sophomore teachers will give great recommendations, but the junior teachers will probably only be good, instead of great. Is it better to stick with great recs from sophomore teachers than good, but not great, recs from junior teachers?</p>
