If you believe that the A0 pin is faulty, there is a quick way to test it.
Make connections as per the following
Gnd to 330ohm to A0 to 10K to 3.3v
Then click on deploy configuration on the Cloud to get an updated data point.
If you get a reading near 33 then the A0 pin is fine.
If you still get a reading of 1.02k please take a screenshot of the same and share it here.
