What is the most valuable thing to put on a Med Application?

Besides the usual work experience, volunteering etc.

2 things.

1. Great exam results
2. Serious reflections on your work experience, volunteering etc. What did you learn from them.

Reflection...

For instance, how you learn that there are several elements of communication when you work with the elderly

so all of it is just:
Grades
Work experience
Volunteering
Extra curricular/ physical activity
Personal statement including strong work exp reflection

What do you mean by several elements of communication?
Thanks

After reflecting on work experience, explain how since a very young age you've always wanted to become it. They look for motivation and a thirst to learn.

Personally, I don't think grades and work experience matter "that" much. I would place more importance on the qualities that you poses and that you can give evidence for via your past experiences with people~

For instance, communication is one of the best attributes to have as a doctor, and one that the admissions team value quite a bit. So if you do some work in an elderly care home, it not only shows that you're an empathetic and caring person -but you can reflect on it on your personal statement saying something along the lines of "I learned that by actually listening to Lynda, I was able to create a strong bond between us and further developed my communication skills bla bla"

So I would place attributes (gained through reflection) much more important that work experience and grades

Good luck with an application without good grades.
