Not too easy. Not too difficult.
The class itself is great and offers a lot of info towards what you will learn in the major. However, the professor i had was unenthusiastic and unorganized. everyday felt like he was going off the top of his head. He was a great head of the department but he wasn't really meant to be a professor in that class. All in all the experience was ok but the class was semi-helpful.
The best part was probably the big project at the end. We got to vote on what we wanted to build and the class got to set the rules and regulations. Afterwards you pair up with others in the class and get to work. for ours we had to build a trebuchet and launch a ball through cups without having the ball hit the ground.

Advice for students:
Pick a well reviewed professor and don't miss any classes. The course was only one day a week for me so if its the same for you make sure you don't miss it. its only one day and not that long. Plus its a fun class so definitely worth attending.
