Hello @FrankieK and @mbarchukov,

I think I know what you have done wrong, see

Wk 2, PA Log. Regr. w/ NN logistic_regression_model not working

I guess you have an error in your model function, where you calculate Y_prediction_train. You are most likely using X_test, which contains 50 examples, instead of X_train, which has 209 examples.
