Consistentcy of scores

I have taken in total 4 practice exams, with two of them being full lenth. On gmatprep my quant was around 39-41, and mgmat quant between 43 and 44. I attribute the higher score on the mgmat tests to the fact that I exclusively studied mgmat materials, while also completing the OG questions. I have scored 590 gmatprep, and 600mgmat twice. Unfortunately my verbal score has fallen from a 40 down to a 30/31, and I think its because I worked so hard to bring up quant and neglected verbal (had math score of 17). Anyway I have scored a 30 on verbal 4 times in a row now, (2 mgmat, 2 gmatprep). Will my gmat score be similar, given my consistency? Thanks.
