I'm posting you the ones I'm really unsure of.

1) The day after their visit I started my homework and I did't manage to finish it before the beginning of the school.
2) On 30 December I was with a group of friends.
I spent the rest of my holiday meeting my friends, doing homework and going to callisthenics practice.
3) On Epiphany Eve the "kindly old woman" brought me many sweets and a pair of earrings. On 8 January I went back to school as all my classmates (did) / like all my classmates.
