I'm wondering whether it is still effective to cold-email professor of interest at this point, are there any opportunities left? I only received one offer from a backup school in the first week this month, and I was asked by the future supervisor to give my final decision within two weeks. So I just send inquiry emails to several other schools about their review timeline, and luckily one of them gave me a reply soon with a fully-funded offer, without any interview. The left ones replied me that I need to continue to wait till early March or even later, and some even suggest me to consider the offers I already received if I haven't been contacted at that time. Actually, I didn't receive any update from all the five PhD programs that I mostly want to go, no rejection, no waitlist, no interview, so desperate, I'm afraid they'll come together next month. Oops, I just received my first rej when I finished these words...
