Remember that if student have more that 5 "clases" and scored B+ in each one score will be 200 points

ohh understood thnx

If there are 5 or more courses and all courses has a grade of B or above, additional 20 points are awarded.

Because of that, name4 has a "C".

why name3 got 160 and name3 and name4 has equal length of array and name3 score is getting 20+ extra because of length so why name4 should not?

total += points.get(score) 

That line is in your code, isn't it? Read the error message:

TypeError: unsupported operand type(s) for +=: 'int' and 'NoneType' 

Not a kata issue. Print the input to debug your code.

name4 should not get +20 at the end

The question is not relevant. I figured out what's wrong.

array = [
["name1", 150, ["B", "A", "A", "C", "A", "A"]],
["name2", 120, ["B", "A", "A", "A"]],
["name3", 160, ["B", "A", "A", "A","A"]],
["name4", 140, ["B", "A", "A", "C", "A"]]
]
name4 A3=303==90+B1=20+C1=10==120+20 (20) OF LENGTH WHY STILL IN OUTPUT?

It would not make sense if the tests for the task were displayed in more detail. And so, I'm at a loss as to what I did wrong. I originally found a solution, it passed the tests. I decided to do a little refactoring. After that, the new solution fails the tests.

Is there a point to this post?

more and all courses has a grade of b or above ;) kinda confused thnx

If there are 5 or more courses and all courses has a grade of B or above, additional 20 points are awarded.

can anyone explain me why name3 of sample cases not in output he scored 140 but actual score is 160

oh thanks, got it

no one can get more than 200 points, it's just a rule. if you have more, it is "downgraded" to 200. so jack got 200 points
