2 of my recommenders are my profs who taught me UG physics and math, they know me very well and will give me good recos.
but my third recommender is the prof under whom i did my summer project. Now the problem with him is that although he was very pleased with my results and encouraged me very much (he even said "you just need the opportunity, you can do wonders") but more often he used to say "you are doing fairly well", or "you have done well". Its his style, his words of appreciation are of moderate level. Now i am having trepidations about this word fairly, some sources on the internet say that fairly well is equivalent to no good. will this botch up my chances of getting admitted?
or i have another math prof in my arsenal

what do you guys think i should do?
