Hey, I am facing the same issue. I have my test in less than 10 days, and the whole city is in lockdown. Pearson test center didn't pick up the phone. I wrote GMAT an email today requesting them some information, or at least allowing us to cancel the exam free of cost.
I really worry though about the situation. In conditions of lockdown(for now it is till May 3rd), obviously they will cancel the exam free of cost. But, in case the government doesn't extend the lockdown, I really fear that test center might open up and we'd have to give the exam in such tragic times(risking our health) ! I really fear going out considering the healthcare crises Delhi is facing, lack of oxygen etc. Would be $250 in drain, and I can't afford that. But, what is more precious than our life !
I mean, if the center cancels the exam, they might do it just a day before to be honest(from what I heard from some of my friends). However, I would really appreciate for them to let me cancel free of charge considering the bad crisis, so I can book an online date at the earliest.
I think that is the most humane thing to do, at the very least.
I am waiting for their email response for now. Other than that, GMAT has been pretty much unavailable.
I will keep you guys updated. Kindly update as well, in case you hear something useful.
Regards
