3 sciences, with labs, is a very rough go. Add calculus (unless you took calc in high school & did well), and you're overloaded for your first semester. You can do 2 sciences with labs each semester, but 3, especially your first term, is probably too much. You have a lot of other adjustments to make your first semester. And do English first term - you need to be sure your language skills are top-notch to write papers & everything throughout. So perhaps 2 sciences with labs, calc, English, and one elective for your 5 courses.
