What skills have you gained from your part-time job?
Think about what you are currently doing, or have done previously, during employment.
It doesn’t matter if the job is relevant to your chosen course - the admissions tutors just want to find out what you’ve learned, and how you can apply it to your degree.
For example, you might have a job waiting tables in a restaurant. You could talk about how working under pressure when there are lots of customers will help you deal with the study workload at university, as well as exam revision periods and making sure you meet deadlines.
You could also talk about how working as part of a team will help you excel in group activities during your studies.
Other skills could include numeracy, IT, using your initiative, communication, solving problems, etc.
Write down several aspects of your job where you have learned new skills, and how they might prove useful on your course.
This is a chance to reflect on your experiences and show the admissions tutors what you can bring to the table.
