Ooh I'm not an expert on that unfortunately, but I'd say given the circumstances you'd be perfectly fine to show your interest and enthusiasm for the subject through other means (e.g. books, lectures, videos etc. and what you took from them/what they led you to look into or want to study more).
Does it matter if I don’t have any work experience in my personal statement?
Hiya!
We have an "ask me anything" thread open for personal statements questions ran by our Student recruitment team that is open for just today! Ask them any questions as they see thousands of personal statements so have lots of hints and tips
