Stuck at challenge labs tasks 2 and 3 GSP341

[Elixander]

Trying to complete the 'Create Models using Bigquery ML: Challenge Lab' but getting very mixed scoring from the progress checks.

For instance, task 2 requires to evaluate the model using ROC on unseen data. I've done that but kept getting the error that it's not completed (more on this later).

So I proceed to the rest of the tasks (getting 0 for the rest). Last task requires you to run a prediction using the model. I ran the evaluate method instead, yet the assessment completed for this task when it shouldn't have.

I executed the progress checks again, now task 2 is suddenly completed while task 3 is stuck at 15/25.

Bit puzzled with what's going on, could use some help please. Thanks!
