    I am a GBN graduate and I find that I am much more prepared and capable of my college classes than my peers. I hated GBN with a passion when I was there but going away to school has truly shown me what GBN gave me. That being said there is an incredible need for A's. I was a B student but I always felt terrible around my A earning friends. I didn't take AP classes therefore I was a sub-par student. It was terribly stressful. I felt alone at GBN; though they say there's a club for everyone I never quite fit. But that is just me. I did have great teachers for the most part. They will go above and beyond if you ask them for assistance. But you have to advocate for yourself or you'll fall behind. All in all it is a good school.

    I attended this school years ago and not a day goes by that I don't use some bit of knowledge culled from my exceptional high school education. Fabulous district with unbelievable resources. A top-notch education and facility. Northbrook remains a wonderful place to live because the schools continue their tradition of excellence. Bravo.

    Glenbrook North was an ok school. It wasn't what I thought it would be it's not the grates school at least the way I was treated there. I was discriminated against by some of the staff I had to go through a lot. they diden't even give me my sat score after I graduated

    GBN is an amazing school. There are clubs sports and the arts to support any student's interests. Totally prepares students for post-secondary education. However it lacks majorly in diversity. The school tries but when your population is so homogeneous it's difficult! I didn't appreciate it at the time but after undergraduate and graduate school I very much appreciate all my teachers did for me!

    I love Glenbrook North. Glenbrook North prides itself on its 3 AI LOVE Glenbrook North. Glenbrook North prides itself on its 3 A's Academics Activities and Athletics and they do a good job at each. As for the Academics a few years back they switched to block scheduling you have 8 classes 4 of those classes one day and the rest of the 4 classes the next day. It gets the student prepared for college schedule wise when they won't have the same schedule every day in college. In addition students don t have as much stress because there won t be as much homework on a daily basis and periods are each 90 minutes in length which allows for greater opportunities. You ll find there are no negatives in a 90 minute period some critics say that 90 minutes is too long but the teacher doesn t lecture for 90 minutes straight a lot

    The programs are great. It's the students that need some work. I would rather teach students that are more down-to-earth.
