If your scale is what was typical when I was in high school, translate each 9 or 10 to a 4, each 8 to a 3, each 7 to a 2, each 6 to a D, and each 5 or lower to a 0. Do that for each grade and calculate the average.
If your high school uses 0-100, 90-100 = 4, 80-89 = 3, 70-79 = 2, 60-69 = 1, and anything under 60 = 0.
Why are you interested in studying in the USA? What do you want to do with a psychology degree? If you want to work as a psychologist, with a degree from the USA be any better career-wise than a degree from Tel-Aviv, Hebrew U, or Ben-Gurion?
You should also think about whether you would fit in a college. College in the USA is a very different experience than in Israel, and the students are very different than the people around you, especially by way of age and life experience (you’ll be 20-21, after military service, and they will be 18, just having graduated high school)
As for finances - remember that college, for the most part, is far more expensive here than in Israel. I think that annual tuition at Tel Aviv University is under $9,000 a year. Have you looked that the tuition for the colleges on your list, the chances of merit, and the amounts of merit?
Room and board are expensive, especially if you are going to be in NYC or Chicago.
I just want to make sure that you really have an idea as to what you’re getting into.
PS. how does your Bagrut look?
