Elin was moving from a large primary with 300 pupils to Ysgol David Hughes in Menai Bridge, whilst Ffion was moving from a small primary, with just 19 pupils, to Ysgol Dyffryn Nantlle, Penygroes.
Neither of the girls knew each other, but they shared a lot of the same hopes and concerns.
Elin - September 2005:
It's been quite a sunny day and I've been playing with my little brother Ifan who's three. There are 36 of us moving from primary school to Ysgol David Hughes in Menai Bridge which is five minutes on the bus from where I live.
I'm most looking forward to making new friends and learning a new language, either French or German.
I think the other lessons I'll enjoy most will be music and history.
I've been to the school a couple of times before and on a practice day. I'm still slightly nervous; I hope all will go well tomorrow.
Ffion - September 2005 (end of first day):
I was not worried about anything in particular, only maybe which bus to get on at the end of the school day as there were lots of buses at the bus stop. I am looking forward to meeting new friends after being in a small school.
My favourite lesson has been French because we have been doing French for two years at small school, so it felt good that I could already speak some French before the lesson started.
Both girls got up at the crack of dawn on the first day, but had slowed down by the end of the first week.
Elin: Up at seven this morning and out at the bus stop by 8.10. My first lessons were English then PE. I was looking forward to wearing my new kit, but we didn't change today.
After break it was maths, where we did adding problems and adding bingo. Next, up the stairs to computers. I managed to get a bit lost, but found my way in the end. I didn't get lost on the way to dinner though. I beat the lunch traffic jam and chose my favourite - pepperoni pizza and chips.
After lunch it was RE then Welsh. The Welsh class was near to the buses so it was easy to get there on time.
Ffion: Yesterday I got up at 6.30am, but this morning I got up much later as I was still tired. I was looking forward to going back. I was much happier today about the buses and where to go for lunch. I also learnt that they have a shop, where you can buy biros and pencils and things if I forgot anything - this made me feel happier.
We had PE today. In small school there were two boys the same age as me and we had PE with the other, smaller, children. In big school only girls of the same age as me had PE at the same time. The children who knew each other passed the ball to each other, but no-one passed the ball to me.
I was worried about getting to the right place at the right time, worried about where the toilets were and whether I could find them and get to lessons on time. This is not something I've had to think about before.
Overall however both felt the first week was a success.
Elin: Just a few weeks ago I was still in primary school and when I passed David Hughes School I used to think how huge it was. In just a small amount of time I've grown to feel more at home and am becoming a bit more confident. I think it might have helped coming from a larger primary school, but the children from the smaller ones seem to be settling in fine, too. I shall miss my old primary school, but shall still go there from time to time as my little brother starts there next year.
Ffion: I liked everything. It was all new and exciting, scary to begin with, but good. It was good to find out new things like book clubs, school forums, choosing house captains and house teams.
Three months on, how's it all going?
