Passing the Kaplan Secure Predictor B?!

Hey guys. So I "graduated" my nursing program a month ago. I failed HESI (870)and Kaplan Secure Predictor A (59). I have to do a remediation program where I take Kaplan Question Trainers 1-6, the NCLEX sample tests, and 800 Q bank questions and hand remediate everything I get wrong. Then I have to take the Secure Predict B.

I'm just very stressed and worried about getting the 63% benchmark because if I don't, I have to retake my practicum course. I definitely cannot afford to go back to school. I have until Feb. 19th to complete everything and have finished Question Trainers 1-6, NCLEX sample tests 1-3, and did my first set of 75 Q bank questions. I was wondering if anyone had any tips for studying? I feel like I'm doing all these questions, writing down all these answers, and I'm not retaining anything? I'm very paranoid. Here are my scores so far:

Question Trainer 1: 59%

Question Trainer 2: 59%

Question Trainer 3: 48% (yeah I know, terrible)

Question Trainer 4: 60%

Question Trainer 5: 55%

Question Trainer 6: 65%

NCLEX Sample 1: 62%

NCLEX Sample 2: 64%

NCLEX Sample 3: 77%

Q Bank 1: 53%

I just don't know what to do or how to study. I'm not sure what my problem is. I don't know if it is content or that I get distracted too easily, or if I'm simply terrible at the Kaplan Decision Tree and eliminating things. Is there anyone with tips or who had similar scores with positive outcomes? Thank you so much!
