I Declined a PhD offer because I thought tuition was £21k instead of £5k.
I did an interview for a funded PhD project and the professor said I didn’t get the funding but I should consider a self funded one if I want. I asked him for the breakdown of the cost and he said that it would cost about 25k for the tuition and then other costs for the visa and accommodation costs would also be done by me. He mentioned that there is a funding that there is a high chance of getting that would reduce the tuition to 5k, for some reason I read the email as reducing the tuition by 5k, making it 21k. So I replied that I could not continue with that amount. It’s been about 8 weeks and I decided to look at his email again and just noticed the mistake I made. What do my chances look like if I send an email saying I made a mistake in declining.
