Hey folks!
Hope you are all having a great weekend

I just wanted some help about a particular situation I am having. As you all know, the classical GMAT version ends on the 31st January (in 2 weeks basically).
I have been studying for quite a while and I have already a sitting scheduled in 2 weeks. However, as I want to secure the highest mark without having to go to the Focus version, I was wondering if it would be wise to schedule another sitting for this week. So, just to confirm:
1) Is it possible to buy another sitting if we have already booked one, or would I run into any sort of problem?
2) The 16-day period between exams is only for the same format, right? As in this case the first one would be online, I guess there wouldn't be any trouble.
3) Is there any other factor that I should consider in order to perform this strategy?
Also any tips/advices would be greatly appreciated

Thank you so much for your help guys!
Keep well everyone!
