Are UW questions and FA enough to pass the exam?

I have read the materials two times and then stopped to study for three months for family reasons. My exam is in May 31th and I can not extend it anymore (did once already).
what do you advise me to do please? Do i have time to read the materials one more time from kaplan? or just do questions from UW and read the explanations plus First Aid.
I am desesperate because I feel i do not remember more of the stuff when I do the UW questions.
