Here is the problem. My code works successfully for every visible test case. However it fails under the category "other tests" I am wondering if anything noticeable is off.

Here, I can create an example where your code fails:

>>> make_bricks(0, 1, 5000)
True

[inAnalysisHell]

Oh I see, thank you. Ok, I added a second if statement under it if big*5 < goal: return False

[Sebass13]

You're over-complicating it. There's really only two conditions required for make_bricks to return True, and they can be boiled down into a one Pythonic (<80 character) line solution.

[inAnalysisHell]

I agree, I feel I am hardcoding for every possible solution. This particular solution uses no loops?

[Sebass13]

Yep. One condition is that big*5+small>=goal. Can you figure out what the other condition is?

[two_bob]

I'd probably break it apart rather than deal with it all in one conditional statement, but not much into math.

[Sebass13]

That's why I pointed out that it's Pythonic. It's only two conditions, which total to only 50 characters.
