how would you translate " los estudios que realicé"

Question

and would you spell it realicé or realizé ?

é

Answer 1

One suggestion:

I have made courses on biology = He estudiado biologìa

I made studies in your field of knowledge - Realicé estudios en su área de conocimientos.

---

All verbs ending in -izar (izar, realziar, alunizar, ecc.) end in -icé when conjugated in preterit, 1 person

Answer 2

": the studies that I've done." (realicé)
