Hi, I'm the person behind H1 Biology Notes.
I made these notes the way I wish they'd existed when I was doing Leaving Cert Biology myself — clear definitions, key notes organised the way the syllabus actually teaches them, and a fillable worksheet for every chapter so you're not just reading, you're actually testing yourself.
Every chapter follows the same structure: Definitions, Key Notes, and a Fillable Worksheet, built to the H1 standard and kept up to date with the new 2027 specification as it rolls out, chapter by chapter.
I'm not a publisher and this isn't an official resource. H1 Biology Notes is independent — made by one student for other students — and it's not affiliated with the State Examinations Commission, the NCCA, or any textbook publisher. It's a study aid to help you learn the material properly, not a substitute for class or a guarantee of any grade.
Notes are delivered as an instant PDF download after purchase — no waiting, no shipping.
Questions, or something not working right? DM @H1BiologyNotes on TikTok — I read every message myself.
