Hi pmorfire.
Do you truly believe you are ready to achieve your GMAT score goal if you take the GMAT now? Many people take the GMAT to sort of see how they will do before they're totally confident that they are ready, and rarely do they hit their score goals. In other words, the GMAT is rather good at identifying your skill level. So, it's unlikely that you'll luck into scoring high on the GMAT.
The reason I'm asking is that I see that you've already taken the GMAT five times without being prepared enough to achieve your score goal, and you have only three attempts left. So, if you're not rather confident that you will hit your score goal if you take the GMAT within the next few days, then probably you should hold off and take it when you're more prepared.
Just my 2¢ ...
