I'll jump in and give you an answer. From 7th to 10th grade I attended a majority black school (a common "solution" to No Child Left Behind in the south eastern US was to move accelerated programs (IB etc) to the lowest preforming school to keep averages above the level required for funding). There definitely was tension (probably exacerbated by the academic divide on top of the racial one) most noticeable in interactions with the administration. Neither group having any incentive to integrate lead to a general feeling of "otherness" but I couldn't say I remember any overt prejudiced on the level experienced by people in the inverse situation.
