Step 2 CK
For step 2 CK the scores are generally reported within 4 weeks, so you can take it as late as mid August and still have the scores available for the opening of the match. Since there are often delays in reporting during this busy time, it best to be safe and get your exam done by the end of July!

Summary:
Get CS done by July 18th 2020!
Get CK done by end of July (best) or the latest by August 15th 2020!
Key to Success: Getting Great Scores is the ultimate key to opening doors. So take it when you are the most prepared and likely to get your best scores!!!
