Nursing License!??

Hi There,

I am here in US since 2 years.It almost took me 1 year to do my credential evaluation and enter into exam process.I studied saunders and practiced 2000 questions.My performance was ok during preparation.But i haven't studied for 4 years and i studied seriously for 15 days because of work.When i sat to give the exam,the questions were not that tough.But unfortunately i failed.Now its getting more and more overwhelming for me.What if i give the exam and not pass it again.I have limited time to stay in US and already 2 years have passed.I have enrolled myself in nclex-on demand.Its overwhelming,can't memorize all lectures,can't note it down.It has short time access.I am really scared about my 2nd attempt. Plz suggest me with some ideas??
