How did you use these resources? Did you watch Kaplan/DIT passively? Annotate in FA? How are you using UWorld?
If your scores are low across the board, I would assume your foundation is weak. My personal suggestion is for you to read a section of First Aid ACTIVELY. This means talking things out, looking up mechanisms if you don't understand why x causes y, and memorizing details (use a notecard to cover something up and then recite it). Once you finish this, watch the relevant Pathoma chapter if you want. Then do some questions, say 40 UWorld questions, on the subject you just finished. As always, read the explanations thoroughly and then go back and find the information in FA to see why you missed a question. Doing this thoroughly will take ~3 weeks.
For pharm and micro, I suggest you use SketchyMedical. Sprinkle it in with each FA section or watch a little every night before bed.
Once you finish one pass this way, start doing random 40-question blocks until you finish UWorld. By this point, you've at least seen all the material at least once so random questions will refresh your memory. Maybe re-watch a little Sketchy every night to keep the pharm and micro fresh.
I think this would put you in passing range in 6 weeks or less.
Edit: Ditch Kaplan/DIT. Use FA, UWorld, Sketchy, and Google. Pathoma once while reading FA.
