this is the MPrep CAT folder, so, any problem in this folder is from our CAT exams.
these problems don't have native "problem numbers", since the presentation and order of the questions is different for every individual test taker. (e.g., problem #3 on one person's exam #2 might be problem #14 on another person's test #5.)
our exams come with answer keys, so, there would be little point in presenting solutions in "full detail" here. the purpose of this forum is to address specific questions about specific aspects of the problems -- NOT to serve as a surrogate answer key. (anyone who's bought the exams will have access to the answer keys!)
thanks.
