Many JAMB candidates believe that studying at night is the best way to prepare. The quiet environment, fewer distractions, and sense of dedication often make it seem like the perfect time to focus. But while night study may work for some, it doesn’t work for everyone. In fact, it could be harming your retention, energy levels, and overall performance without you realizing it.

If you’ve been struggling with late-night study sessions, it may be time to rethink your strategy. Let’s look at why studying at night might not be the best choice for JAMB 2025 and what you can do instead to improve your performance.

1. Your Brain is Less Effective at Night

You might feel like you’re being productive at night, but your brain doesn’t function at full capacity when it’s tired. After a long day of activities—school, chores, or even social interactions—your mental energy naturally decreases.

When your brain is fatigued, you may experience:

• Slower comprehension – You take longer to understand concepts.
• Weaker memory recall – You forget what you just read.
• Difficulty focusing – You get distracted more easily.

Even if you spend hours studying at night, you might not retain much of what you read. This makes night study less effective compared to morning or afternoon study sessions, when your brain is naturally more alert.

2. Lack of Quality Sleep Hurts Your JAMB Preparation

Studying late into the night means you’re sacrificing sleep, and this hurts your ability to retain information. During sleep, your brain processes and organizes what you’ve learned. If you don’t get enough rest, your brain doesn’t store information properly, making it harder to recall during exams.

When you’re sleep-deprived, you might experience:

• Memory loss – You forget key concepts you studied.
• Brain fog – Your thinking feels slow and unclear.
• Reduced problem-solving skills – You struggle with calculations and logical questions.

Over time, lack of sleep can make your study efforts feel useless, because your brain simply won’t retain much of what you learned. To avoid this, it’s important to follow a well-structured study plan. Check out How to Prepare for JAMB 2025/2026 UTME CBT Examination for effective preparation tips.

3. Studying at Night Encourages Procrastination

Many students say they will study at night, only to postpone it repeatedly. Throughout the day, you may keep telling yourself, “I’ll read later at night.” But when night comes, you feel tired, lazy, or distracted—and end up either skipping studying or doing it half-heartedly.

This cycle can make you:

• Keep postponing study sessions until it’s too late.
• Cram at the last minute, leading to poor retention.
• Feel guilty for not studying properly, which increases stress.

If you struggle with procrastination, relying on night study may not be the best option. Instead, a structured daily study plan will help you stay consistent and avoid unnecessary delays.

4. JAMB is Written in the Morning – Why Train Your Brain for Night?

JAMB exams are held in the morning and early afternoon. If your brain is used to working at night and sleeping during the day, you’ll struggle to perform at your best during the actual exam.

When you suddenly have to wake up early for the exam after weeks of night study, you may feel:

• Drowsy and mentally sluggish.
• Unable to think fast and recall information quickly.
• Less focused, leading to careless mistakes.

To match your study habits with JAMB’s timing, you should train your brain to be active at the same time your exam will take place. That way, when exam day comes, you’ll be sharp, focused, and fully prepared.

5. Negative Health Effects of Night Study

Staying up late every night to study might seem productive, but it can damage your health over time. Constant sleep deprivation and overworking your brain at night can lead to:

• Increased stress and anxiety – You may feel overwhelmed or panicked.
• Weakened immune system – You’re more likely to fall sick.
• Frequent headaches and eye strain – Especially if you’re reading on a screen.
• Mood swings and irritability – You become easily frustrated.

If your JAMB preparation is making you feel constantly tired, stressed, or sick, your study habits might be doing more harm than good.

6. What to Do Instead: A More Effective Study Plan

If night study isn’t working for you, don’t force it. Instead, try a smarter study plan that helps you learn effectively without harming your health or memory retention.

Study When Your Brain is Naturally More Active

For most students, morning and afternoon are the best times to study. Your brain is fresh, and your body is well-rested, making it easier to focus and retain information.

Use Evenings for Revision, Not Heavy Learning

If you must study in the evening, don’t try to learn new concepts—your brain won’t process them as well as during the day. Instead, use evenings to revise what you’ve already studied, answer past questions, or go over key points.

Follow a Structured Study Timetable

Instead of random night reading, create a realistic study timetable that fits into your daily routine. Dedicate 2–4 hours each day to study, broken into short sessions to avoid burnout. A great resource to guide you is Proven Study Timetable for JAMB 2025 Candidates.

Get Enough Sleep

A well-rested brain remembers more! Aim for at least 6-8 hours of sleep every night, especially as the exam approaches.

Final Thoughts: Study Smarter, Not Harder

Studying at night may seem productive, but if it leaves you tired, forgetful, and unprepared, it’s not worth it. JAMB is not just about studying hard—it’s about studying smart.

If you’ve been struggling with night study and not seeing results, try switching to a daytime study routine and see the difference. Your brain will be sharper, your memory stronger, and you’ll feel more confident walking into the exam hall.

At the end of the day, the best study method is the one that helps you learn efficiently and perform at your best on exam day.
