Those going to Eisenhower High were excited to finally get into their new digs.
The building has security cameras, air conditioning and a lot more.
The campus is the size of six football fields.
"I think that at this school we're going to have more space for lunch because the other school was smaller, so not everybody could fit in the cafeteria and the lines were long," said Eisenhower senior, Nubia Gonzalez.
"I got lost though, I couldn't find my class," said Eisenhower sophomore, Angelo Salazar.
"It's really big in there and the best thing I like in there is the speakers in the room because we can bump music," said Eisenhower senior, Daisy Gonzalez.
The school is built to hold 2,400 students and cost $108 million.
A new gym and theater are some of the main attractions.
