Remember when taking notes to first divide your page into 4's horizontally as shown in the center below. As the horses enter the arena mark their number and any distinguishing descriptions such as color of horse, size, etc. Note your first impression.  Be sure to label the class at the top of the page before they enter the arena. Leave a place for placing. For each horse quickly note positive and negative points from front, both sides, rear & close inspection.  Be sure to note how they travel from front, rear and side.
