Mest troligt hade Tom studerat mycket.
Det var mycket troligt att Tom studerade mycket medan han var på Hogwarts. Han beskrevs som törstig för kunskap, vilket innebär att han inte bara var naturligt begåvad, han arbetade också för att få mer kunskap.
“As an unusually talented and very good-looking orphan, he naturally drew attention and sympathy from the staff almost from the moment of his arrival. He seemed polite, quiet and thirsty for knowledge. Nearly all were most favourably impressed by him.”
- Harry Potter and the Half-Blood Prince, Chapter 17 (A Sluggish Memory)
Han hade fått högsta betyg i varje undersökning han hade tagit, vilket är ytterligare bevis för att han var en särskild student.
“He reached the seventh year of his schooling with, as you might have expected, top grades in every examination he had taken. All around him, his classmates were deciding which jobs they were to pursue once they had left Hogwarts. Nearly everybody expected spectacular things from Tom Riddle, prefect, Head Boy, winner of the Special Award for Services to the School.”
- Harry Potter and the Half-Blood Prince, Chapter 20 (Lord Voldemort’s Request)
Tom sa också att han litade på att han var en modellstudent.
“It was my word against Hagrid’s, Harry. Well, you can imagine how it looked to old Armando Dippet. On the one hand, Tom Riddle, poor but brilliant, parentless but so brave, school Prefect, model student; on the other hand, big, blundering Hagrid, in trouble every other week, trying to raise werewolf cubs under his bed, sneaking off to the Forbidden Forest to wrestle trolls.”
- Harry Potter and the Chamber of Secrets, Chapter 17 (The Heir of Slytherin)
Från vad vi vet om Toms prestationer, och hur hans lärare och kamrater upplevde honom, studerade han nästan säkert tungt.
