The majority of all sessions missed during the week of 22 February to 26 February were due to an absence directed by the school (code “Y”).
Roedd mwyafrif yr holl sesiynau a gollwyd yn ystod yr wythnos rhwng 22 Chwefror a 26 Chwefror naill ai oherwydd absenoldeb a gyfarwyddwyd gan yr ysgol (cod “Y”).
