Hey, so this may not be overly helpful but it really depends on the uni. They have so many applications to consider that sometimes it can take a while! Mine all came within 10 days with the first coming in 4 days after submitting. I know people who submitted ages ago and haven’t heard back yet, equally, I know someone who got an offer two hours after sending it! The time it takes doesn’t reflect on you, it may be that they have allocated times to look at applications. They may also, as mentioned, have absolutely loads of people apply.
Another thing I’d say is, don’t be disheartened if you get a rejection. What is meant for you won’t pass by you. Again, they have so many applications that it’s impossible to accept everyone.
It is horrid waiting but be kind to yourself, focus on a levels as that is what will get you there anyway! And know that nothing you do can change the outcome now, so worrying about something you can’t control is pointless. You can control how well you do in your exams, or how you treat people, and how you look after yourself- those are the things to focus on.
Good luck, wishing you the best.
