Hi Alvaro,
Back in March, you described your tentative Study Plan (linked below) - did you end up following that plan?
strategy-to-study-215455.html#p1663176Given your score goal and practice CAT scores, you'll likely end up having to retest later on this year. As it stands, there's no harm in taking the GMAT as scheduled (you can cancel the score if you're not happy with it - but if you do, then you should make note of your Scores so that we can discuss them later). The time 'off' will likely impact your skills a bit, but it's unlikely that you'll completely forget everything that you've learned during that time. When you get back, we can talk through how best to prepare going forward.
The Verbal section of the GMAT is challenging for many Test Takers for 2 reasons:
1) There are no 'safety nets' in Verbal questions, so if you make a little mistake you won't be able to catch it (you'll just end up selecting one of the wrong answers).
2) Test Takers are at their most tired during the Verbal section; at some point, you will think "I just want this Test to be over..." and you'll end up putting in less effort, taking fewer notes, etc. and missing out on lots on 'gettable' questions.
Thankfully, the Verbal section of the GMAT is as predictable as the Quant section is, so you CAN train to score at a higher level. This is all meant to say that you really have to learn/practice the proper Tactics, and learn all of the patterns and little 'secrets' to the Verbal section, to significantly improve that Score.
GMAT assassins aren't born, they're made,
