Check Sheet to Aid Memory Retention Thank you for viewing. Originally, there were 8 red sheets, but this time I will include a total of 10 red sheets (including the ones I have at home) and 1 green sheet. In addition, I will include red and green markers and pens for memorization. I purchased these over a decade ago and used them, but the included red sheets, green sheets, and pens are mostly unused. Please consider the above before purchasing. #MemorizationSheet #RedSheet #ExamStudy #Student
