Good Job Amiel!!!! I really like the way put the words in different color but you might put a different color rather than green we can't read because it so bright...... But you did a very good Job!!!!!:)

Good Job Amiel! I like how you made the important words in different colours. You might want to put an image though.

Nice Job! I like how you calculated your answers, but next time, you should add a little more detail. You should also add an image!

Great job Amiel! you should put an image to represent you work. I suggest you should use the color red instead of green because it's so bright and add some more details for easier understanding. Overall, Grat job! keep it uP!
