Hi. I've just left Tonbridge Grammar. I went there from year 7 for 5 years, and I've just started Sevenoaks School to do the IB in the 6th form.
I really recommend going to TGS. The standard's very high and, unless you make friends with the wrong people, you are sure to push yourself very hard and get good results.
If you are thinking about going into the 6th from to do IB however, definitely go to Sevenoaks,( TGS has only been doing the IB for a couple of years).
Also, if you're v keen at sport, TGS' sports facilities aren't great so you might want to look elsewhere.
But TGS is definitely a really good school, and I'm so glad I went there (having gone, I think I'm def more grounded than lots of my friends who have been at private schools all there lives). There is always a great mix of people in each year so you're sure to make loads of friends.
Basc, you really should go. (p.s. I'm happy to answer any questions you have about the school).x
