I have done about 1000Q so far. I am so lost... I have NCLEX in a few weeks.
I have been doing 75 to 150Q on regular basis, but I basically did random by selecting all subjects and all systems. I am getting high 50s to mid-60s, but I feel like its disorganized to me.

Should I do by systems, but mix it up with random too? Please help! I am just not sure what to do at this point.

I took Nclex two days ago and I recommend not skipping subjects. I had OB, peds, med surge, memtal health, etc.

Every exam is different though... I had friends that said 90% was OB others said med surge, some mental health, so that's the tricky part!
