Learn to Program: Crafting Quality Code

Edited: One star. The tests fail you because you can't properly read the question. The tests change subtly each time around. You'll spend 25 minutes on the test, and get 78%, every time, getting different answers "wrong". This course sucks. Maybe if you like pain?

A very good course, let down by the quotes issue!
The tests are fairly good, keeping you thinking, but alas the execution of the website means that every other test question is marred by strings of  everywhere that should show a ' (single quote/apostrophe)

Here's an example:
1. Select the expression(s) that evaluate to True.

o int(& #x27;3& #x27;) in [len(& #x27;a& #x27;), len(& #x27;ab& #x27;), len(& #x27;abc& #x27;)]

& #x27;a& #x27; in [& #x27;mom& #x27;, & #x27;dad& #x27;]

Obviously it should say
Select the expression(s) that evaluate to True.

o int('3') in [len('a'), len('ab'), len('abc')]

o 'a' in ['mom', 'dad']

This is the reason it isn't 5 stars, and it sadly isn't actually to do with the course content. However, it is incredibly frustrating to get an answer wrong, and increases the cognitive load hugely for no reason. Coursera needs to sort it out. And it isn't just me - my wife using her independent laptop and account has the same issue.

Edit: Ok, mind blown! This page actually renders the /' as a ', so I've added a tab so it renders "correctly".
