FRQ (specifically AP econ): What if I write something incorrect?

I heard that if you write something wrong on the first part of the frq, but then follow on it later (ex. you say something is a monopoly but the answer is perfect competition. later they ask you to draw the graph of your previous answer. you correctly draw a monopoly graph and get points for the graph answer) you’ll get points. Can anyone confirm this?

Additionally, would something be counted correct as long as it is there? For example, the question is how much is the economic profit and you say “the profit is 10 dollars. the profit is 9 dollars” The correct answer is 10, would you still get points? It’s kinda of like a lowly trick but upperclassmen told me this a good tip for when you don’t know the answer, I’m not sure if it actually does though and would decrease points.

You would still likely get some points.

I doubt it. Otherwise, people would just write “the profit is 10 dollars. the profit is 9 dollars, the profit is 8 dollars. the profit is 7 dollars…”
