Can you help me with my CV?

So I want to apply to a job, cashier on a supermarket is my first idea. But I am not sure what information to add.
Things I added:
-Personal info like tlf number, email and adress.(Didn't put where I am from or such, I don't find it too important)
-My studies plus entrance exam to university. I don't know if add that the reason I apply for this job is saving up for college.
-My other 2 jobs, I only worked in two places in both as waitress.
-A small summary of how I am as person (nice with clients, responsible, blah blah...)

I feel like it is too brief but after all, it's all I have,12 years of school, entrance exam and 2 jobs.
Can you help me with my CV?
