Harry Potter for Kinect

This achievement is earned during the story line and each segment can be repeated at any time so it is definitely not missable. Each section of each year has an achievement for completing it and earning 5 stars. This achievement is unlocked after you have earned 5 stars in every story line segment. I unlocked it before doing any practicing so the blackboard classes have nothing to do with this.

Each section of each year is graded based on 3 standards. These vary depending on the section. Duels are typically for Spell variety, Accuracy and Avoidance whereas Dodging section are typically Health, Dodging Ability and one other item. At the end of a section you are given a mark out of 100 for each of the 3 requirements. 5 Stars seems to be rewarded for an average of 80 percent or better however there is a lot of variability in that. Typically each section has one or two easy requirements to complete and one that is more difficult.

There is no specific solution for all of the sections however each section has a related achievement so see those if you are having trouble on a specific section. Take each one as it comes, check to see what the requirements are and practice the section until you get the 5 stars. I found this rarely required more than 2 or 3 attempts and I unlocked many of them on the first attempt.
