Great to see a 2022 applicant parent here!
Firstly I wouldn't worry about the amount of clinical experience had by your DD. They were flexible this year, and most likely will be next year as well. That being said, the vast majority of applicants had the necessary, if only just. The time line for this experience varies from school to school, but worse case scenario I think is 24 months so your DD seems to be covered. (But please do check as each school is different, and a little mistake can be very costly!)The online courses were counted as one week or 35 hours in this round of applications, so there again you seem to be doing well.
As for a year out, it's not me that will say it's a bad thing. My DD had school days that started at 5:30 every morning, never getting back before 7pm, combined with high level sport. We made a conscious decision to limit the stress and apply only once she had her grades, but another solution would be to ask for deferred entry. That way, in a worse case scenario you get 2 attempts for the same start date.
This year "off" has been a god send. She's dedicated half her time to her sport, something she'll probably have to stop once at Uni, and also got a part time job in a supermarket. Admittedly it wasn't very glamorous, but with COVID, it's allowed her to get out of the house, spend time with other students, and really grow into a more confident, self assured and mature young adult. I'm definitely less worried about her being a thousand miles away from home next year than I would have been if she'd gone straight out of school. This was just a personal choice, and may not be for everyone, but for us it most definitely was not a wasted year.
Good luck to you and your DD, we are here if you need any advice etc, but you seem to have got the basics well covered already.
