Forest ranger, wildlife officer, conservationist.
Factors That Make These Courses Easier
- Lower Admission Pressure:
Most of these courses are not highly competitive during JAMB admissions. - Simplified Curriculum:
They usually have descriptive, rather than calculative or abstract course contents. - High Continuous Assessment Weight:
Students can earn marks through attendance, fieldwork, and assignments. - Less Laboratory Rigor:
Compared to courses like Biochemistry or Physics, lab requirements are minimal. - Student Support:
Smaller class sizes often mean more personalized attention from lecturers.
Are Easy Courses Worth It?
Yes, if you:
- Have passion for the field
- Prefer a balanced academic and social life
- Want to avoid courses with extreme stress
However, always ensure the course aligns with career aspirations and industry demand. Some of these programs may require postgraduate studies or certifications to compete in the job market.
