AMCAS has changed the rules so it no longer returns applications with significant number of misclassifications. They have also shortened the verification window processing time as I believe they have now linked to the National Student Clearing House system which searches and/or store virtually all college catalogs in the country. Furthermore, making an educated guess on how they have implemented the system, each primary application runs thru software that compares all courses and titled listed to descriptions in the linked college catalogs. This likely has a rules-based/knowledge-based engine that "scores" each listed course at to BCPM or OA as a percentage of likelihood. This may check things like department, terms in the description, etc. It would have various levels of "flags" say score of 75% is automatically accepted, score of 74%-51% need human checking with course in question and its college catalog description popping up automatically for review and , scores of 50% or less gets automatically reclassified. We shall see how this new system works
