Hi. I'm not from Irvine, but I've stayed with a friend who lived there! One of her sons is bright, but had some learning disabilities, and I know he thought classes were really challenging, but her other kids liked their schools. They actually moved to Minnesota right before the oldest started High School, so unfortunately I can't tell you if the Irvine high schools are a lot different than elementary schools. I think if you're an honors student, you'll be fine no matter where you're at. It might take a semester or two to feel as comfortable in school as you do where you're currently at, but I encourage you to join an extracurricular club that's similar to whatever you're involved with now (band, drama, sports, debate, etc.) and by meeting new kids while doing activities you enjoy, you're bound to make new friends soon.
