    This quiz had some activities, and honestly, I never bother opening my book while studying online because of the ‘cheating formula’ (relax, not actual cheating, bachha 🤭). When they say ‘activity,’ I’m always clueless about which one they’re talking about.

    And for the people who think I’m a topper—ABSOLUTELY NOT. Arey bhai, yeh saari mehnat toh sirf Mary Jane’s shoes ke liye ho rahi hai! If it were up to me, I’d happily cheat in the final exam 😅… but this time, I gave myself a big fat NO.

    MARY JANE’S SHOES FOR LIFE 💖🍥!
