Someone might achieve good performance despite poor study habits due to factors like:
* Exceptional natural aptitude or talent: Some individuals might grasp concepts quickly and perform well even with inefficient study methods.
* Luck: They might have gotten lucky on exams or assignments.
* External support: They might receive significant help from tutors, teachers, or classmates.
However, in the long run, and for consistent, high-level performance, good study habits are almost certainly essential. Relying on factors other than effective study strategies is not sustainable. Therefore, while not a strict logical prerequisite, they are a highly practical and necessary element for achieving and maintaining good academic performance.
