Choosing the right JAMB subject combination for Geology in 2026 is one of those decisions you really don’t want to rush. One small mistake here and your admission dreams might get stuck like fossils in sedimentary rocks 😬.
So let’s slow down, break it all the way down, and make sure you’re 100% clear before you lock anything in.
First Things First: What Is Geology All About?
Geology is the science of the Earth — literally. If you’re the type that’s curious about:
-
rocks and minerals
-
earthquakes and volcanoes
-
oil, gas, and other natural resources
-
how the Earth has changed over millions of years
…then Geology is your lane.
Because it’s a pure science course, JAMB and universities are very strict about the subjects they want to see. No vibes, no shortcuts — just science 😌.
How JAMB Subject Combination Works (Quick Reminder)
For JAMB UTME:
-
You must register 4 subjects
-
Use of English is compulsory for everyone
-
The remaining 3 subjects must match your course
For Geology, there are core subjects you must have, and then optional subjects where JAMB or the university allows some flexibility.
This is where many candidates get confused — but don’t worry, we’ve got you.
Core Subjects for Geology (Non-Negotiable)
These subjects are mandatory. If any of them is missing, Geology is automatically off the table.
✅ Core Subjects:
-
Use of English (compulsory for all courses)
-
Chemistry
-
Physics
These three form the backbone of Geology:
-
Chemistry helps with mineral composition and reactions
-
Physics explains earth processes like pressure, heat, and seismic waves
No Chemistry or Physics = no Geology. Simple.
Optional Subject(s) for Geology (This Is Where You Choose)
Now for the fourth subject — this is where JAMB gives you options.
✅ Acceptable Optional Subjects:
-
Mathematics
-
Biology
-
Geography
You only need ONE of these, not all three.
How to Choose Smartly 👇
-
Mathematics → best choice for most universities and safest overall
-
Geography → strongly relevant to Geology and accepted by many schools
-
Biology → accepted, but not as strong as Maths or Geography
If you’re unsure, Mathematics is the safest plug. Period.
Final JAMB Subject Combination for Geology (2026)
✔️ Core Subjects (Fixed):
-
Use of English
-
Chemistry
-
Physics
✔️ Choose ONE of the following:
-
Mathematics (recommended)
-
Geography
-
Biology
That gives you your required 4 JAMB subjects.
Common Mistakes Geology Aspirants Make (Avoid These 🚫)
-
Replacing Physics with Biology ❌
-
Offering Chemistry, Biology, Geography but skipping Physics ❌
-
Choosing subjects based on “what I like” instead of what JAMB accepts ❌
JAMB and universities don’t negotiate subject combinations. Once it’s wrong, that’s it.
Important Advice for JAMB 2026 Candidates
Different universities may have slight preferences, even though JAMB provides the general rule. Before final registration:
-
Always confirm with the JAMB brochure
-
Check your preferred university’s requirements
-
Don’t rely on “my friend said” or WhatsApp groups
Joint Admissions and Matriculation Board will not correct subject mistakes after registration closes.
Final Thoughts (Real Talk)
If you’re serious about Geology in 2026, your subject combination must scream science-focused and intentional. Go with the safest options, not experiments.
Get this part right, and you’ve already won half the battle 💪🌍
