SAT II subject test spanish- raw score needed to get a 560- please advise!

I am a college student who needs to pass a language placement test by scoring a 560 on Spanish.

I know the scores are scaled each year, but I’m looking for a raw score estimate which would be around a 560 on the exam.

I looked at this page (http://p1cdn4static.sharpschool.com/UserFiles/Servers/Server_881339/File/Counseling/SAT%20Subject%20Test%20Resource%20Guide.pdf) and they say that a 560 is a raw score of 50

But in my practice books they say that a 560 is a raw score of ~ 44.

Can anybody give me help/guidance here?
Thank you so much!

Oh, yeah, also I just found this: https://books.google.com/books?id=qRx-BAAAQBAJ&pg=PA7&lpg=PA7&dq=sat+spanish+test+raw+score&source=bl&ots=cKt7lvrRdw&sig=jbNsSxN59iDXPy_p6BEJqbfdU2Q&hl=en&sa=X&ved=0ahUKEwj5qrOoh9HRAhUN24MKHb35AUQQ6AEIUDAJ#v=onepage&q=raw%20score&f=false

from the Princeton Review 2015 guide, it says that for a 560 you need a raw score of 43.

How can I tell which source is credible?

It differs for every test. There’s not a set, exact raw score conversion for subject tests, because the difficulty varies from test to test. It will really just depend on how other people taking the test do. Try to aim for at least 50.

What practice books are you using? I used Barron’s and it is amazing.
