Why would it be GOOD for you to switch? Where do you want to go? Why?
I’m a mom of an 18 year old boy, and what would persuade me more than anything else is a clear, well-researched list of pros and cons of all of your educational options.
Find out what the percent of graduates who go on to a 4 year university is at your school, and at your optional school. Find out the crime rate - how many times have kids been arrested or expelled at each school? Find out the cost difference - don’t limit this to the current school year. True, your current school is expensive, but does going there strengthen your chances of getting a scholarship to a good college? Your mom may be looking more long term than you are.
Look into non-tangible pros and cons. Is the other school close enough to walk to, instead of Mom driving you everyday? (I don’t know if she does, just trying to think of every angle of advantage and disadvantage here.) Would that give you extra exercise? Does the other school offer any extra-curricular activities, clubs or teams that you find interesting? Those things look good on college applications!
Does the other school have AP classes or subjects like Physics or Calculus that your current school doesn’t have? AP classes can get you college credit while you’re in high school. Sometimes public schools have better lab classes than private schools, even expensive ones, so even if your school offers physics, the public one might be a better class. Or not. This is research you have to do.
Most of all, try not to make your mom feel bad for sending you to your current school. If you harsh on it too badly, she’s likely to get defensive, and that makes people really unwilling to change. She’d basically have to admit she was wrong, and people don’t like to admit they’re wrong! Instead, focus on the positive things you find out about the other school.
Also, ask her why she made her choice. She may have had great reasons for it that she never shared with you. Maybe it will help you see the advantages of your current school, or maybe not. But it *will *give you some insight into what’s important to HER, and addressing that is more likely to affect change. If you’re focused on meeting girls, and she sent you to that school because she didn’t want you getting distracted by girls, that’s not the best way to change her mind! While social development is important, and going to a co-ed school can help with that, what I’ve read on this board about “Asian parents” (and I totally apologize for the broad stereotype!), focusing on academics instead of meeting girls will probably go over way better.
If my son showed me through solid research why he wanted to change schools and how good it could be for him, I’d know a few things. First, I’d know what’s important to him. But more importantly, if he did a lot of work to gather the information, I’d know it was really important to him, and not just a whim or a bad week at school. That alone would make me take him more seriously.
