Hi,
Last year I applied 5 schools for PhD and all have rejected me. I was a little bit late to apply. I completed my application in January and tried to contact in mid-January. Sent mails to 11 prof. and only 2 replied me. One of them said that he would take a look my application. The other prof usually do interview with all candidates in February, so we did it. At the end, I have not been accepted.This year, I will again apply for PhD. I will add other schools to my options. However, I would like to add some schools from previous years list.
Is it fine to send an e-mail to a potential PhD advisor even he did not reply to my e-mail last year? If so, should I send in August or September or when?
