My advice is to take detailed notes while watching the videos. Also, make sure to read the manual carefully. If you initially believe a dimension falls into the high range, refer back to the manual and review the criteria for that range. If what you observed doesn’t align, move down to the mid-range, and continue adjusting as needed. This process takes time, but it’s the most effective way to ensure your observations, notes, and final score are accurate and well-supported.
