Are there any programs like COSMOS?

-Are not competitive
-have financial aid or are cheap (preferably but please let me know of any that aren't necessarily cheap)
-don't require you to go home over the weekend
-Last several weeks
-focus on STEM
-are in California (preferably but not necessary)
-accept sophomores juniors
-offer college enrichment (teach about college requirements etc)
I am going to apply for MITES next year but I'm obviously not going to make it altho its worth a try!
Thanks and have a good day! :)</p>
