so far I have : 1 anatomy/physio (Bio) 1 bio/academic adviser, 1 CIS professor who knows me better than the others, and 1 dentist... I plan on getting one from my physics professor during summer I... so that would total 5 LORs.. I'm having all of them saved in my schools credentials service, since i'm not banking on getting in this year... is it bad to send 5 LORS to each school? and if I have them sent directly, do the professors need to send any additional information to match up my LORS to the rest of my app? they will be sent with a copy of my transcript since there's no way to not send both with this service... thanks!
