It's not uncommon to wait a few months for offers, my first took two weeks to come through. Give it time.
Yes, it is true..But the wait is terrible! I Hope to have news soon.
I applied a month ago to exactly the same universities for marine biology! Until now I have already received an unconditional offer from Glasgow! Edinburgh Napier, had gotten back to me about fees. At the moment the status is 1 offer, 4 still waiting...
I have a question! My first choice was actually Glasgow, because it is in the Russell Group, high employment rate, high ranking for biosciences, larger city, and cheaper living cost than St. Andrews. I'm curious what your choice is. :3
