How prepared do you feel for your Topic 5: Mid-Topic Assessment?

• I am so ready! I have studied and I am feeling confident.

• I feel okay about this, I have studied and solving two step equations makes sense to me.

• I am a little confused still, I should probably study more before I take the assessment. If I spend more time reviewing, then I will feel more confident.

• I am really confused still. I should go to my teacher's office hours for extra help.

• I have no idea what I am doing and I don't have any solutions to help me prepare. (If you select this choice, you should email your teacher to let them know how you are feeling!)
