Step 1: Eat Well the night before your exam and on the day of the exam
Avoid food that can give you toilet worries. You don’t want to be put under pressure.

Step 2: Take only allowed items
You’ll need at least 2 color copies of your JAMB exam slip. You are to submit one to the invigilator while you keep the other one for reference purposes.
You may need a Biro. You might probably not use it. But just should in case, you may need it.
Do NOT bring in bags and electronic devices such as phones, calculator

Step 3: Go to your centre early
Don’t put yourself under the pressure of rushing especially in the city avoid putting yourself under the stress of traffic leave home before traffic hour.
Get familiar with the centre environment. Find out where the hall is located. Make sure you know where the rest rooms are, where you can keep your belongings in case you are with one and maybe fire exit.

Step 4: Avoid negative candidates, Believe in yourself
Some candidates are afraid or might have failed the exam in the past and they are at the centre spreading fear and failure to other candidates. Stylishly flee from such people. Don’t let them mess with your mindset
It is true some candidates write JAMB more than once, but some candidates also write it just once.

Don’t be pressurized into cheating as well, we believe in you as the future of the country.

Step 5: Ensure your Bio-metric (Thumbprints) Verification is done at the examination centre
It is COMPULSORY. you do this. If it is not done, ask for it.

Step 6: Read and obey instructions
I repeat Read and obey instructions.

Thanks op.
My own piece is PRAYER.

Thanks for sharing Op. But the print-out slip does not necessary have to be the coloured one. The black copy is allowed too. But it has to be the original copy.
