Choosing the right JAMB subject combination for Geophysics in 2026 isn’t something you rush in five minutes. This course sits right at the intersection of physics, earth science, and real-world problem solving—think earthquakes, oil exploration, groundwater detection, and environmental studies. So yeah, JAMB takes it seriously.
Before we even talk about subjects, let’s slow down and understand why certain subjects matter and why others are optional but powerful.
Why JAMB Is Strict About Geophysics
Geophysics is not just “science”—it’s applied physics on Earth. Universities expect candidates who:
-
Are solid in calculations
-
Understand forces, waves, energy, and fields
-
Can apply science to real-life earth processes
That’s why Joint Admissions and Matriculation Board doesn’t joke with the core subjects for this course.
Pick the wrong combo and… yeah, admission vibes = cancelled 😬
The Non-Negotiables (Core Subjects)
These are the subjects you must have, no debate, no shortcuts.
✅ Core Subjects for Geophysics (JAMB 2026)
-
Use of English (Compulsory for everyone)
-
Physics
-
Mathematics
Let’s break that down real quick:
-
Use of English: You already know the drill. It’s compulsory for every JAMB candidate.
-
Physics: This is the soul of Geophysics. Waves, magnetism, electricity, mechanics—everything connects.
-
Mathematics: Calculations, modeling, data interpretation… if math isn’t there, the whole thing collapses.
These three are locked in. You cannot remove or replace them.
The Flexible Slot (Where JAMB Gives Options)
Now here’s where many students get confused.
JAMB requires four subjects total, so after the three core ones above, you’ll need ONE more subject. This last subject is optional, but not random.
🎯 Approved Optional Subjects (Choose ONE)
-
Chemistry ✅ (most preferred)
-
Geography
-
Biology
Yes — you choose ONE, not all.
How to Choose the Best Optional Subject (Smart Talk 🧠)
Chemistry (Highly Recommended)
-
Best option for students targeting top universities
-
Aligns well with earth materials, minerals, and energy studies
-
Many universities quietly prefer it
Geography
-
Great if you’re strong in physical geography
-
Helpful for earth structure, landforms, and spatial understanding
-
Accepted by many universities, but not all
Biology
-
Less common but still acceptable
-
Works better for environmental or interdisciplinary paths
-
Not every university prefers this, so always double-check
💡 Pro tip: If you’re unsure, Chemistry is the safest bet.
