小白求求大神答疑 NYU phd 不cover全部学费要不要去 买上DLL了

小弟 收到了NYU的Phd offer 给的RA 一个月3300，但是给我的letter里说的是Tuition remission of up to the larger of (i) the minimum number of credits per semester
required to maintain full-time status, or (ii) 6 credits per semester plus applicable fees
and health insurancefor yourself.
我目前也不是很清楚这个会不会很坑啊 求求大神解答

没看到哪里说不cover全部学费
