Ok so I'm very rural borders, specific questions welcome but will try and give overview.
Primary's ok, most places. High schools earlston and Peebles are the two sought after, Peebles was recently burnt down though. In temporary use until new one is built.
Berwickshire coastal but comes with issues as PP mentioned. Drugs rife here at moment, across area really but coastal towns have had some publicised issues, as have Hawick, gala, Kelso.
Duns and Kelso have new high schools, both ok but can be bullying, I suppose like anywhere.
Hard to give a good picture at moment as everything so unusual. All kids given iPads from upper primary and work sent home during covid was minimal. Wifi is patchy, not always reliable, super fast broadband being rolled out in some places.
Agree Melrose nice and many from there use earlston high rather than galashiels. Or they go private. Also has the train link from tweed bank.
If I could live anywhere, having been born and bred here I would move to Northumberland or up north way.
