When you say the phrase 'without a doubt' you mean that something is obvious or very clear. Notice the following:
- He was, without a doubt, the worst teacher I ever had.

I almost dropped out of school.
When you drop out of school, that means you quit school or you stop going to class. A drop-out is a person who quit school. Notice the following:
- My father was a high school drop-out but he still went on to succeed.
- I dropped out of college to help my family when my dad got sick.
The course was way over my head.
When something is 'way over your head' that means it is too difficult to understand. For example, in school a lecture or chapter from a book can be way over your head if it is too hard to comprehend. Notice the following:
- What she was saying was way over my head.
- I took biology, but is was way over my head, so I dropped out.
He's been involved on and off since the beginning.
When something happens 'on and off' that means it happens, and then stops, and then continues again. Notice the following:
- My relationship with my girlfriend has been on and off since I last saw you.
- The plans to build a new bridge have been on and off for awhile.
We plan to branch out and try new things.
When you branch out, that means you experiment and take risks and try new ideas. Notice the following:
- This year I plan to branch out and explore new areas.
- The restaurant plans to branch with a new international menu.
