Got to study about Guevara (7)
I believe the answer is:
reached
'got to' is the definition.
('reach' can be a synonym of 'get to')
'study about guevara' is the wordplay.
'study' becomes 'read' (synonyms).
'about' means one lot of letters goes inside another.
'guevara' becomes 'che' (revolutionary Che Guevara).
'read' enclosing 'che' is 'REACHED'.
(Other definitions for reached that I've seen before include "Cad here (anag.)" , "Stretched or arrived" , "Attained" , "Came to (a place)" .)
