Please don’t give up!Remember not to pull yourself down.
Some of us take a little bit longer than others by using a different approach to get certain concepts down. Does your teacher provide tutoring at any time? Have you tried Kahn Academy?
We’re still in first semester. Ask for help from everywhere. You might also consider asking another teacher, who teaches the same thing, for help.
Please don’t stress about colleges right now. Please focus on your current classwork and don’t come down on yourself. What other people do at one time, may not be what they do later. So don’t focus on others, but focus on building yourself up! I’m sure you’re a lot stronger than what you think you are!
