Usualhopeful, Ratings are relative. The OP is asking if UCLA’s program is mediocre. Implicit is a comparison with others. I believe Stony Brook has the highest ranked (Using US news ranking) CS program in SUNY. It has a reputation rating placing it at 40. (Bing is 112; buffalo is 63; Albany is 101) That is quite good. But UCLA is listed as 13. Calling UCLA mediocre would mean those 30 or 100 slots down the list are considerably below mediocre. But UCLA isn’t mediocre. It is outstanding. So that elevates those down the list too.
