NCLEX (RN) HELP (using archer to study)

Today is June 14 and my test is scheduled for July 3. I have 20 days until I take my test.

I am using archer and listening to Mark K.

I scored borderline on my baseline assessment, and I have taken 4 readiness assessments so far scoring high, low, low, and borderline in that order. I have also taken one CAT exam and failed it. I don't know what to do because for the most part it feels like im guessing on everything.

I am so frustrated because I did well in nursing school, however I feel like once I studied the material for a test in school all of the information left my head because I immediately had to start studying for another test. I am afraid I have to relearn 2.5 years of nursing content in 20 days and I don't know what to do. Everyone says to read the rationales but I feel like that doesn't help me because nothing sticks since it's a completely different category/subject for each question.

I need to pass this test because I am scheduled to start my residency the same week. PLEASE HELP!!!
