My eldest dd is in her first year and started after she did a BSc degree first, but that is a long and expensive route.
We couldn't get direct work experience in our local hospital due to having the wrong postcode, but I would suggest taking anything
you can get your hands on even if it's not directly related, such as working as a pharmacy assistant ( My dd also did two weeks with a dentist,
), but with this you could still talk about learning about the benefits and disadvantages of electronic prescriptions, patient confidentiality (she saw prescriptions of people she knew), some of the main common problems affecting the area, learning how to work as a team, dealing with angry customers
it also improves knowledge about common over the counter medications, but the biggest bonus is getting to actually also talking to the pharmacist on duty .
Secondly I don't think it's too early to go to open days if you have the time ( I work for a London university- so I am biased and love open days) . You actually get the chance to speak to current medical students as well as tutors and get to know more about the course and what it actually entails.
