The majority of all sessions missed during the week of 8 February to 12 February were due to an absence directed by the school (code “Y”).
Roedd mwyafrif yr holl sesiynau a gollwyd yn ystod yr wythnos rhwng 8 Chwefror a 12 Chwefror naill ai oherwydd absenoldeb a gyfarwyddwyd gan yr ysgol (cod “Y”).
