This appears to be a table to log how well the student is doing in certain lessons, by noting where they rank in the class. I’m glad that this isn’t significant in school classes these days! The lessons in the table headers are Classics and Mathematics, with a space to add another. Peggy has only made one entry, on February 13th, for piano. She crossed out ‘place’ and replaced it with ‘stars’ and wrote in ‘1’ in the Marks column. There are two more identical pages in the diary, which Peggy left blank.
