Thank you @lkg4answers. I might try to get into CCS, after going there and exploring.
Thank you for the information @gumbymom . Yes, that’s what I have read on the UCSB that you have to have the senior undergrad standing and showcase with the upper-level courses. I guess its similar across UCs. Looking at the UCSB though there doesn’t seem to be limit and quite a few courses are open for undergrads.
THanks @firmament2x. This is great information. Thanks for sharing. It definitely gives the perspective for me to make a final call.
