She scored 1 / 3 marks less in science in the first semester than the second, which is 1 / 3 * 90 = 30. Her score in science in the first semester is 90 - 30 = 60. The total for the first semester is 90 + 75 + 60 = 225. The total for the second semester is 90 + 90 + 80 = 260. The combined marks for all the semesters in 260 + 225 = 485.
The final answer: 485.
