Short answer

IB Diploma is generally harder than IGCSE. IGCSE is a secondary qualification (age 14–16); IB Diploma is a pre-university programme (age 16–18). They are different levels—IB is more advanced.

IGCSE comes before both IB and A-Level. IB Diploma is comparable in level to A-Level—both are pre-university. Choose based on your school, learning style, and university goals.
