Q. Do they need to learn degrees or will they only need to do right angle turns (90 deg)?

A. Yes, the kids will need to know degrees in Scratch. There is a turn right by x degrees, and a turn left by x degrees command in Scratch. If they turn in either direction 90 degrees, this will complete these turns.

Q. Is there a list of the Scratch commands they will use or how should coaches decide which to teach to make sure the kids know how to use?

A.No there is not a list of Scratch commands with which the students should be familiar, per a previous question:

• “For Section C of the event, students will be expected to solve a movement-based task. They will be asked to navigate a sprite around a provided background using appropriate language constructs from Scratch. The event will not require multiple sprites and students will not be required to sense proximity to obstacles programmatically. We’re looking for basic familiarity with Scratch, not complex code.”
Q. For the first part of the test, will there also be examples that are for example both Input/output (an iPad)?

A. For the Computing Basics section, we will not intentionally provide an example with an ambiguous function such as an iPad being both input and output.

Q. And for this part is the name of the device going to be in the image in case the image is not clear? (For example, memory card vs network card)

A. For the Computing Basics section, we will identify the hardware or software using names and/or pictures as appropriate to the question.

Q. Are the students expected to create code that, when one button is pushed, their sprite makes its way through the provided obstacle course, or are they meant to create code that allows the sprite to be controlled by arrow keys?
A. The expectation is that the students will provide code that navigates the board, not that they will provide controls for someone else to navigate.
Q. Will the background that they are going to be maneuvering their sprite through be 2d (looking down on a walking surface, for example), or 3d?

A. The background will be 2 dimensional
Q. Is there a preferred or required method of movement that they should use to maneuver the sprite or of controlling the speed of the movement?

A. Students should use the appropriate language constructs in Scratch to maneuver the sprite.
