Yes, I just started and the instructor notes follow the old v3.3 kit. There are only some minor differences, and with that said, I downloaded the old v3.3 SIK manual and just cross reference between the two. Hope that helps.

I also received the 4.0 kit, and have completed all the units requiring the 3.3 guide.

I followed along the best I could using the 3.3 guide and doing the workbook exercies, that could be done with the provided kit, and where I couldn't I simply said so. You can check out my weblog, to see more clearly what I did.

hi there

I just started the course, and I have taken the other approach, before having seen your comments.  I received version 4.0 of the kit, and downloaded the errata pdf from their website.  I am following the 4.0 exercises.  

From what I understand of the assignment requirements, no specific experiments are required, but examples that contain certain parts and actions to demonstrate understanding.

Here is the quote from Assignment 1 (with the link after):

• Your weblog should contain designs, discussion, and diary entries that describe working examples which demonstrate exercises and concepts covered in Unit 1 and 2 inclusive
• Working examples will include moving actuators such as motors, turning LED lights on and off, and sensing light levels.
