objectives, which are to:

1. demonstrate sufficient knowledge of the concepts of the diversity, interdependence and unity of life;
2. account for continuity of life through reorganization, inheritance and evolution;
3. apply biological principles and concepts to everyday life, especially to matters affecting living
things, individual, society, the environment, community health and the economy.

THIS PART OF MY POST IS FOR THOSE WHO DON'T HAVE MONEY TO

SPEND BUT HAVE TIME TO STUDY.

Anyone Who Tells You Jamb 2025 will be hard is absolutely lazy or deceitful,
Jamb 2025 is no different from previous Jamb exams so long you're prepared
for it. *JAMB IS THE EASIEST O’LEVEL EXAM IN NIGERIA*

What do I advise Candidates to do?

If you can't Afford a good Tutorial, stick to Your *ORIGINAL CBT Past
Questions(2014-2024)* and *JAMB 2025 syllabus* , and spend the last
3weeks to the exam with familiarizing yourself with all the questions and
solutions In JOA CONSULTS *SPECIAL JAMB CBT 2014 - 2024 PAST
QUESTIONS AND SOLUTIONS MATERIAL*

There's no way you'll read And Familiarize yourself with the *JAMB
SYLLABUS, Original CBT Past Questions(2013-2024) and the
recommended textbooks* and Fail, if you've done that and Failed before,it's
not natural..

IF YOU NEED JAMB 2014-2024 CBT PAST QUESTIONS AND ANSWERS

FROM ALL DAYS AND SESSIONS(hard and soft copy) SEND ME A

(SECTION THREE)

PART ONE: *( PAY TO GET YOUR OWN CBT EXAM QUESTIONS AND
ANSWERS)*

THIS PART IS FOR THOSE WHO WILL READ BUT NEEDS A BACK UP(I
CALL THIS THE HELPER PACKAGE).(RUNZ, EXPO, CHEAT, DUBS)

YOUR QUESTIONS AND ANSWERS CANNOT BE GOTTEN A DAY

BEFORE THE EXAM SINCE THE USE OF CBT IT BECAME IMPOSSIBLE,
THE ONLY THING THAT CAN BE GOTTEN A DAY TO THE EXAM IS THE
ENTIRE QUESTIONS JAMB WOULD SET FOR THAT EXAM DAY. THAT IS
WHY SOME TUTORIALS DO OVERNIGHT FOR THEIR STUDENTS ON
THE EVE OF THEIR EXAMS, THEY ARE SOLVING THE ENTIRE
QUESTIONS JAMB WILL SET THE NEXT DAY.

SO WHEN CAN WE GET YOUR OWN QUESTIONS? FOUR HOURS TO

YOUR EXAM TIME.

The Good Part About This Is, It's Affordable But The Catch Is Your Success Is
In Your Hands, I'll Give you the EXPO HOURS BEFORE THE EXAMS (your
very own Questions and Answers JAMB 2025) That will Help You Pass, All
you have To do is Take A Few Hours To Your Exam To Read It ,Cram it
Extensively, I Beg you Don't Take anything to the hall if you do you're on your
own, after all it's a university you want to attend you must be able to read, so if
you're paying for the questions and answers package know that you've to
read it.

We also create Videos and Audios with the questions and answers sent to
candidates so you wont get bored easily, so you can request you get the
answers in Audio format , Video format, PDF Format ..

Our aim is to make sure anyone who associates themselves with JUST
ONCE ASSURANCE CENTER, scores above 300 and Get Admitted to the
university. When you succeed it's still you that will refer us To others and keep
us in business.
