From your question, what I understand-
- You probably told about Upwork test.
- You scored well in a test and later you could not pass the same test when reattempted.
If this is your case,
- Your first test result may be seen public.
- You also can choose after any test whether you want its result goes public or remains provate.
Every time you complete a test you'll receive a new score and will have the option to display it instead of an older one. All test results are individual and are not merged with previous scores.
