Hi.
I am happy you've decided to practice before taking CLD exam itself. Let me leave some notes about the project you shared.
Usually there is a document explaining the functionality of the code you need to write, also it includes specifications, requirements and limitations you need to follow up. It will be easier for us to review your code having this document or at least some written information explaining your project.
You have LV components structured inside the projects. However, those weren't organized in file structure. It'd be great if you had folders created for each group of LV components (control, subVI, etc.).
You don't have good comments in your code, nowhere. That's a critical miss that can reduce significant amount of score from your final CLD score. As of now, for CLD it is enough to have a single comment block for each VI explaining and covering whole logics of your VI.
There are no error/no error case structure in your subVIs. It is not a mandatory, but just a safe option and best practice to wrap up your whole code in one. In case you get some error from outside the VI the logics inside won't perform until the application is shut down.
When you enter the exam expect a more complex task which will require more extensive code/solution. I wish you best luck in your preparations and in passing CLD.
Best, Ararat.
