Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Eva learns for two semesters in a year. In 2019, she scored ten more marks in maths in the first semester than the second, 15 marks less in arts, and 1/3 marks less in science in the first semester than the second. If she got 80 marks in maths in the second semester, 90 marks in arts, and 90 in science, what's the total number of her marks in all the semesters?

### Response:
Eva scored 80+10 = <<80+10=90>>90 marks in maths in the first semester.
She scored 90-15 = <<90-15=75>>75 marks in arts in the first semester.
She scored 1/3 marks less in science in the first semester than the second, which is 1/3*90 = <<1/3*90=30>>30
Her score in science in the first semester is 90-30 = <<60=60>>60
The total marks she scored in the first semester is 90+75+60 = <<90+75+60=225>>225
The total marks she scored in the second semester is 90+90+80 = <<90+90+80=260>>260
The total number of her marks in all the semesters is 260+225 = <<260+225=485>>485
