Don't get pissed off man! Relax for a couple of weeks before beginning to work again. You do have a lot of room in improving your Quant Score. I'd start grinding on the basics and later move on to OG11
, challenges and MGMAT tests. The MGMAT quant books should be of good help.
I don't see GMAT prep in your practice test list. Have you not given them? They are the best to get a realistic assessment.
Keep focussed, regularly give practice tests to see where you stand, idenfity and work hard on your weak areas, and you be set to achieve your target score.
Good luck !
