To select cells that are not adjacent to each other one way to select them is to click control and to highlight the cell ranges. In the font group on the home tab you can change the font, colors, and borders, with your cells selected.
I don't remember too much things but i just remember I had a lot of trouble with charts, and formulas. I struggled with setting the formulas up because it told me to set a specific range but when i did that it just didn't seem right. We hadn't seen a plethera of things which made it much more difficult. I can't point out these certain things because of my memory. It was hard to take the test in the environment we were in because there were lots of distractions. The eighth graders, random people coming in. It was good when i took the test after school because it was serene and I was really calm. If we had studied a bit more i think we could have been ready.
