So to be clear, we expect most students to very comfortably pursue the standard edition of the P set, but for this particular P set, and we have about 150 or so of these out on the hallway, and we'll have them at office hours throughout the coming week--this is a little logic board ; with lots of sensors; the sound sensor, a light sensor, a little joystick and the like.

我希望我们大多数同学,研究问题集的标准版本，可编程版有个特殊的问题集，我们会在接下来的几周里，在办公时间为大家做解答,这是个小的逻辑板,上面有很多传感器;,包括声音传感器，光传感器，小操作杆等。
