Help me remember a book series

i was going through good reads a few days ago and found a series i found interesting but i can’t remember it now.

Here is the description of book 1 from what i remember:

A girl wants to be a knight but only boys can become knights so she dresses up as a boy and enrolls in the academy for knights and her brother also enrolls in some school from what I remember and in book 2 her best friend is a prince and he knows her secret. (Magic might also be involved but idr for sure)

please someone help me find this it’s been bugging me for so long
