One and half month study schedule for JAMB Exam Using 321exam
- Study 5 hours before lunch and 5 hours after lunch. This is the maximum that you should study in a day. I do understand that this might not be possible every single day. So, on the average, if you can maintain 7-8 hours every day for a month and half before the exams, that will work well.
- Pay close attention to your course instructors, pause the video, replay if necessary and take notes.
- Ask questions in the course forum, attend webinars and attempt the Computer-Based-Tests multiple times.
- Sleep 8 hours at night with a 30-minute nap in the daytime.
- Exercise in the morning and a walk in the evening.
- Frequent breaks, fresh air, stay hydrated, and eat decently.
- Draw up a timetable to ensure you study the 4 compulsory subjects evenly.
