HELP! Self review or Review center..

Hi! I am so confused on whether staying on self review or enroll in a review center before I take my NCLEX.

So here's a little info about me:

- I graduated in the Philippines, and still here until the NCLEX

- Above average student but needs to read the materials 2-3x to fully understand

- I depend on the ability of the lecturers, if they are boring I wont understand even a bit, but if they're great I am a fast learner

- I'm a family man

- Used all available resources just to take the NCLEX.

- Motivated to pass the NCLEX!

I really need to pass in one take, which is making me more anxious.

I am currently on self review. The books that I have bought are Saunders Comprehensive 5th ed, Saunders Q&A 4th ed, Kaplan Strategies, LaCharity book. I didn't want to overwhelm myself with too many materials so these are the only books that I got. Should I buy other books?

Now I can't decide whether to continue on self review until I take my exams, or to enroll in a review center to gain additional info and confidence.

I really need advice!

Thanks!
