really not sure if another prep course and spending money is required. look at the sections you scored low upon, and work thro those sections past year problems multiple times .. to see what you were missing.
very often it is interpretation, your writing (you think you wrote everything, but the guideline answer tells you otherwise). Emphasis on certain words in the question and in your answer may make that big difference.
And finally I think Marc Lefebvre’s coaching - through his LevelUp classes might be the necessary tonic you need. See if he has classed in the NY area, and when. Give yourself sufficient time to read thro and understand all the nuances in the material before your class, and be prepared for a big jumpy ride for the 3-4 days the class is on. Also do not get overwhelmed in the class, he goes fast, but has laser sharp focus. (I should say - I attended his class in 2012 in Nebraska, and did not pass until two years later in 2014. After the 2012 class in April - I got too overwhelmed with trying to do too many things at once, and forgot the curriculum. In 2014 - I focused primarily on the indiv and inst. investor AM sections trying to get at least in the middle range 51-70 on those sections across the exam – and that helped though I did not smash the afternoon section). After 2012 I did not take ANY live prep class, just focused only on the curriculum and supplemented with notes externally.
