Ich habe Deutsch in der Grundschule, im Gymnasium und an der Universität studiert. Spanisch habe ich doch nicht studiert. Mein Bruder hat es doch studiert, aber nur ein bißchen
This is what I can interpret without a dictionary (rusty from 12 years):
I had German in high school, in gym and studied it at University. I had Spanish [but?] I didn't study it. My brother had it and studied it, but [knows?] a little.
ah, just looked up nur and doch. I was close. Grundeschule is primary school? We just called it schule...und kindergarten.
