Spanish CLEP in 3 months; Need a 50 Please Help! Question at bottom!

[therealgageb]

Hello Spanish speakers. I'm in a bit of a pickle. I need to score a 50 on the Spanish CLEP exam so I can get the 6 credits I need to finish my liberal arts degree before I transfer to my 4 year in January. I want to take the test in December so I have really have 3 months to study . I have been on Duolingo for most of the summer and I have about 8100 xp. I have also been listening to this podcast Coffee Break Spanish while I'm at work which has been pretty helpful.

But I feel like this is definitely not enough. Im going to take the REA practice exam tomorrow so I can get an Idea of where I'm at... but realistically I know I'm way off course. I know for sure I need to get my reading comprehension way up. I've been looking for resources all night and the most promising ones I've found have been Spanish Hour (though it looks old and janky), Modern States, and the college board CLEP Spanish Study guide. I also found this reddit post with lots of helpful readings helping with grammar and conjugations. https://www.reddit.com/r/clep/comments/e7jb7x/passed_spanish_with_a_70/But

But I don't know where to start and I need to know what is the best resource or at least where should I focus my study to get that 50 in December??? Please help before I freak out!!
