@fifthending you have to basically compare your itemresponse report to your answer sheet, both are available. i scored my sections last night, i just printed out my bubble sheet and compared it to the IRR and graded it like any other!
I canceled my score for the September exam and I still got a copy of the exam.
If you login to LSAC >>LSAT Status, it should be under LSAT Documents. The sections are in PDF form and the correct answers are under ItemResponse Report.
