How to pass the exam?

To pass the exam, you must be able to write Python code which solves exam problems. You also need follow our exam rules and understand how we evaluate your solutions.

The exam format is described in Course Policies, and some questions in the Frequently Asked Questions also cover exam details. You can test your understanding of the format and rules with the quiz below.

In the second half of the course, we practice solving exam problems and testing solutions. You can explore real problems from past years in Previous exams.

a)

A pdf document with the exam tasks.

b)

A pdf document with the exam tasks, and test scripts.

c)

A pdf document with the exam tasks, empty files for the solutions, and test scripts.

b)

Only numpy, math and os modules.

c)

All modules from the Python standard library.

d)

There is no restriction on the modules.

Question 4

What should students submit during the exam?

a)

The solution files and the test scripts in a zip file.

b)

The solution files in a zip file.

c)

The solution files as individual files.

d)

A Jupyter notebook with the solutions.

Question 5

What should each file with solutions contain?

a)

Only the function and class definitions.

b)

The import statements (if any), the function or class definitions, and nothing else.

c)

The import statements (if any) and the function and class definitions. The code where the functions are tested can also be included.

d)

The import statements (if any), the function and class definitions and the comments explaining the function.

Question 6

The exam task requires that the function returns one of the following values: 'normal', 'night', or 'rush hour'. You made typo and your function returns 'nigth' instead of 'night'. Full points is 10, how many points will you get?

a)

If your function is otherwise correct, you will get full points because the mistake is tiny.

b)

If your function is otherwise correct, you will get 9 points because you only made one mistake.

c)

Your function will be tested on 10 inputs, and all tests affected by your mistake will fail. Since there are three possible return values, you will probably miss about a third of the points.

d)

You will get zero points because the function does not return the correct value for some of the tests.

Question 7

The exam task requires that the function returns a numeric value computed from the input. You made a mistake in the function and instead of returning the value, you print it. Full points is 10, how many points will you get?

a)

If your function is otherwise correct, you will get full points because the mistake is tiny.

b)

If your function is otherwise correct, you will get 9 points because you only made one mistake.

c)

If your function is otherwise correct, you will get half points because you printed the value instead of returning it.

d)

Your function will be tested on 10 inputs. Your mistake will affect all tests and you will get zero points.

Question 8

The exam task requires that you write a function called best_value. You made a typo and called the function bedst_value. Full points is 10, how many points will you get?

a)

If your function is otherwise correct, you will get full points because the mistake is tiny.

b)

If your function is otherwise correct, you will get 9 points because you only made one mistake.

c)

If your function is otherwise correct, you will get half points because you used a wrong name for the function.

d)

Your function will be tested on 10 inputs. Your mistake will affect all tests and you will get zero points.

Question 9

During the exam you run the provided test, and it fails. What should you do?

a)

There is probably a mistake in the test script. You don't need do anything.

b)

You should check whether your code runs correctly for your own tests. If it does, you can ignore the failing test.

c)

There is almost certainly a mistake in your solution. You should check your solution and read the exam task again.

d)

You should correct the test script and run it again. Keep doing this until the test passes.

Question 10

During the exam you run the provided test, and it passes. What can you conclude?

a)

Your solution is correct. You can submit it and move on to the next task.

b)

You should still double-check the function name and the file name, as the test is not checking these.

c)

You solution might be correct, but you should make sure that it works for all inputs.

d)

You don't need to check your imports. The test has already checked that your only use the allowed modules.
