The drive became more than a repository. It was a living classroom. Students argued politely in comment threads about preferred textbooks. They corrected mistakes—an errant dosage here, an inverted diagram there—and thanked each other for catching it. They shared shortcuts for remembering the branches of the aorta, little mnemonics composed in the bored brilliance that only caffeine and impending exams can create. Someone uploaded a hand-drawn flowchart for the management of diabetic ketoacidosis that Arjun studied until the ink blurred.
