I applied more than one univ, but only got one offer at the moment. This is not the best one, but they keep contacting me very actively recently and it seems that they want to get everything straight on the way quickly.They will even contact ors next week, but I want to wait for some replies from some other universities. I feel ashamed to turn this univ down as well, so what shall I do? send virus to the supervisor to damage her e-mail box or computer?
