If the student’s score is 100 or if he has a “Free Pass Card”, he gets an an “A+”. But if his score is from 70 to 99 he only passes. We have two variables: “score” and “hasFreePass”. There are two options of codes:

Option 1:

1 if score == 100 or hasFreePass then
2 print("You got an A+")
3 elseif score < 100 and score >= 70 then
4 print("You passed")
5 end

Option 2:

1 if score == 100 or hasFreePass then
2 print("You got an A+")
3 elseif score >= 70 then
4 print("You passed")
5 end

Notice the difference in “line 3”. Why shoud I do “Option 1”? I could simply do the “Option 2”, because elseif checks if the variable does not meet the “if” condition but meets its condition, so there is no need to use “and”! Well, the lesson tells me to do “Option 1”!

Accept what the lesson gives as a solution and your ability to find it; and, pat yourself on the back for refactoring. It’s the second skill one needs to learn after solving something in the first place. The course is what it is. What you do with it is up to you. Keep this in mind and don’t expect every lesson to be an exhaustive expose of the concept. All in stride, and all the more reason to expect to advance on what you have learned.

Well… true… I lost a lot a time trying to find out, and, when I forgot this and kept doing other lessons and just then realized that it was not the course’s error: I have forgotten a important detail! It was my error! Well, thank you, helped me a lot!
