Not able to view one of my practice tests on khan academy

I am not able to view practice test 5 ,that i attempted yesterday on bluebook, on khan academy. Although i am able to view all other practice tests that i attempted, this particular test is not opening. Usually when i wud click on "Practice on Khan Academy", it wud redirect me to the khan academy page where i can review my test but in this test it is redirecting me to"https://www.khanacademy.org/digital-sat". Plz provide me a timely suggest( as my sat is scheduled on 5 oct) ,as to how i can fix the error
