Practice Exam 2 should be about linear regression and exam 3 should be logistic regression.

Hey Thiha, Thank you for your contribution! We will fix this issue as soon as possible. Kind regards, 365 Hristina

There are some errors such as no correct answer in the choices in the exam questions I think. You should add the `report` feature in the exam questions.

Hey again Thiha, Could you please refer to the questions that you think are incorrect? Are they from Practice Exam 2? Thank you! Kind regards, 365 Hristina

Hi Hristina, Not from the practice exam. Course Exam 'Mathematics' No. 14 - A * A^T , I think answer should be [[18,9,26],[9,5,14],[26,14,45]]. It is not contained. I may be wrong. Course Exam 'Machine Learning with Python' No. 25, I think it is a typo error. It should be 'All but one advantage and one disadvantage are incorrect' instead of 'correct'. Sorry if I am wrong. Thanks.

Hey Thiha, Regarding the Mathematics exam, you are right. We will correct this mistake. Regarding the Machine Learning with Python exam, the interpretation of the answer is "All advantages and disadvantages are correct with the exception of one advantage and one disadvantage." However, we realize that the current formulation of the answer might be confusing, so we will rewrite the question such that there is no misunderstanding. Thank you again! Kind regards, 365 Hristina
