Any tips on keeping calm on your first ngày of high school?

Just be yourself.
Be friendly to the new people bạn meet, and try and become Những người bạn with them!
I remember the time i first started secondary school/ high school , i was soo scared cause i new nobody!! But after a while i found friends! So bạn just have to take a few deep breaths and walk into the school with your head held high, that will make bạn feel confident and calmer ;) good luck!!
And its fun , so enjoy yourself!

TBH on my first ngày of high school I was really shy and just sat it the corner alone... no one wanted to be my friend... but as soon as i started being my loud bubbly self loads of people wanted to be my friend!!

so just be your self and enjoy it xx
