Background:I took a diagnostic GRE early last year (01/2017) with minimal prep just to see how things went. Scored Q:160, V:163, AWA:5.

I'm targeting a Q:165/V:165.

Current study schedule:I have been studying extremely rigorously (2-4 hours every weeknight, 6-8 hours every weekend day) over the past 3 months with an exam date of late July.

I went through the entire Nova bible of math (not great to be honest), have gone through all

Magoosh lectures and have taken about 60 pages of notes, have done 350 V/Q questions on

Magoosh, and I have just begun to go through a couple of sections of the 5 lbs book of problems by Manhattan prep.

Practice Exams:They are going catastrophically poorly.

4/28: Manhattan Prep 1- Q:160, V:162.

5/28: Manhattan Prep 2- Q:161, V:161

6/02: ETS PowerPrep 1- Q:166 V:165

6/10: Manhattan Prep 3- Q:161, V:160

6/16 (today): Manhattan Prep 4- Q:158, V:163.

I know what people say about the ETS being the best indicator but that still doesn't mean that I should be scoring 8 points lower on Quant for the Manhattan exams and have a negative trend. It is far more likely that the Powerprep is an outlier than all 5 other exams being wrong. Furthermore,

Magoosh score range has me in Q:158-163 and V:160-165, fairly congruent with the Manhattan exams.

My morale is extremely low from this. I'm virtually unchanged or WORSE compared to my cold diagnostic test, and this is after ~3 months of hard prep

Other info:I am already taking detailed notes and understanding why I got problems wrong. I even do a deep dive if I get the problem correct but take too long or have a sloppy method of solving it. The problem is all of the problems seem so different...

My pacing can be pretty bad; some of the Manhattan prep exams can leave me way short of time at the end.

Request:Any suggestions on what I could do in the next 45 days to change things up? I am considering looking at GMAT content as well, but I'm completely at a loss for how to handle the way forward.

Is it just not feasible to bring my score up anymore?
