Unless you have a basic grip on some of the core issues it will be very difficult to achieve anything with Grasshopper. Even understanding small networks will be tortuous if you don’t know about the various data types, or how data is structured into larger collections, or how these collections can be modified.
Grasshopper is basically programming and I can absolutely understand that it is not everyone’s cup of tea, or that it can be frustratingly difficult if not explained properly. This could be a problem with the quality or quantity of instruction you have received, or maybe you’re confused because you have some fundamental misconceptions about how you think it ought to work and nobody has figured out how to disabuse you of them.
Either way, it sounds like you have to talk to one of your teachers or alternatively read/watch some other instructional material. Some stuff has been collated here, but I do not know what to recommend for total entry-level instruction.
