I had LR, LG, LR, (break), LR, RC

My first LR was legit.I screwed up the second LR. Does anyone know which section was the experimental one? If the second section was not the experimental, I am thinking to cancel my score. I remembered my first LR had 25 questions, the second LR had 26 questions with the last two pages containing 5-7 quesions.I don't remember how many questions were in the third LR section but I knew the last two pages contained only four questions.
