Just to take on your phrase "this information (on the low scaling of Legal Studies) was always readily available".
First, I am dubious about your definition of what should be considered "readily available" information. Acknowledgibly, legal studies scales low is a consensus fact, and I had no intention to ignore it when I had my subject selection back in year 10. However, documents on how the scaling works or which subject is considered "scaling down" are virtually absent from any easily accessible OFFICIAL sources, namely the Board of Studies and University Access Commission websites. I am sure, also, that most of the students (including you) obtained information on the scaling of Legal Studies from words of mouth, regardless if these words are from teachers or other students.
Second, the consensus "fact" that legal studies is a poor scaling subject is not always immuned from disagreements. I asked a question about scaling for Legal Studies in my recent thread (
http://community.boredofstudies.org/showthread.php?t=182992). The divergence of opinions expressed in those replies merely shows the tip-of-iceberg of how much we are unfamiliar with the courses we are undertaking. The severity of the problem, I consciously remind everyone, really says something about the transparency of the BOS information espcially with regard to the scaling of subjects.
