I would say unless you are planning to re do the yr 12 then don’t, I mean it’s still early to change but some sixth form/ collages might say it’s too late and you have to try the next year. Friends wise, you can still contact your old friends and make new ones. Changing from one exam board to another might be pretty hard. I had a similar thing going on, I’m supposed to be in yr13 but I had to re do yr 12 simply because I changed collages. I got into a private sixth form in bursary but the they changed the fees a bit and my parents couldn’t afford it, so last yr around late October I wanted to change but my current collage said it had be the yr after. It was honestly sad at the end because at first I was like Yh I don’t mind since I’m a summer baby so age doesn’t matter, I’ll have an extra year to gather more experience and my friends are all at that collage. But by the end of the year I made some really close friends (best fronds even [we are still in contact like everyday ] that I actually felt pretty sad. Either way it depends on how much you and your friends are willing to stay in contact. Another thing to consider is if you already like the exam board and the grades your working at. I did bio, chem, psych and maths and at the end of yr I got A,A,A,A which obviously felt like a bummer because now those mean nothing. Also the collage I go now does 3 subjects max, so originally I dropped maths because I was better at psych and enjoyed it more. However, I changed from psych to maths because psych is Edexcel here and I was used to AQA since I did that and the content for Edexcel is more boring. Now I pretty much had no choice, but if I did I would not have changed sixth form. But you don’t have the same problems. I would say talk to someone and do it quick before you don’t have the chance to change sixth forms. I would also consider is the sixth form your going to actually good, teaching wise and support, because as much as social life is important that is also hugely important. Also I would like to mention, even though I was fine in the vigourous schedule in the private sixth form, the more laid back attitude is a lot more relaxing (I mean to be fair I know all the content really well so to me it’s not as scary). I agree, I mean before I had barely time to relax we were flying through content so fast and teachers assumed we knew everything, on top of all that we were simultaneously doing 2 topics at once, and it was new to me then. Now I like the pace and the support more. It was so exhausting ( I would say private sixth forms are always way more exhausting than normal sixth forms).
So what I’m trying to say is, since money is not important to you, think about the cons in moving would provide, and if your okay with it then the difference in education and extra stuff. Does your private grammar sixth form has better opportunities and education ? Or is it the same? Or is the other sixth form better ( you would be surprised by the fact that my now collage is somehow so much better than a PRIVATE sixth form in terms of education AND opportunities)? I would also consider, if the schedule and environment is effecting your grades (by extension mental health) , because at the end of the day the grades (by extension mental health) are important and lastly it would genuinely help you more by meeting your friends again and if your struggling making new friends, (also I would like to say I joined that private school AT sixth form and made friends with the other new sixth from students, which might be different for you because you’re there since high school, so consider that) and then talk to someone about. And final advise for sure is whatever you do DO IT FAST, before your chance goes away.
Hope this all helps, and good luck.
