Count Number Of Consecutive Rows Of Equal Value?

I'm looking at test results and would like to know how many times in a row correct answers were given before getting one incorrect. The way I have this currently set up, is if a student has the answer correct it returns a "TRUE" value, and a "FALSE" value for an incorrect answer. A typical test may have 50 questions, so I would have either "TRUE" or "FALSE" values in rows A1 through A50.

So I've been trying to figure out a formula that counts the number of times "TRUE" rows repeat 'consecutively' in a given column, in this scenario column A. The formula would need to check the current row and if "TRUE" check the row immediately after, if that row is also "TRUE" then check the row immediately after that, until it runs into a "FALSE" string, then display that total count of consecutive "TRUES" in another cell. I understand there may be duplicate results but I'm only really interested in the longest value, so duplicates can be ignored.

If it makes the formula easier, each possible result can be assigned to it's own cell. Let's assume the test has 50 questions. So if a student got all 50 questions correct the result count would be 50 in cell B50, or if they got 25 correct before the first incorrect answer, cell B25 would say 25, etc. I'm guessing I could then easily query this column for the largest value to come up with what I need at a glance.
