My Leaving Cert subjects were Irish, English, Maths, French, Chemistry, Biology and Business Organisation. My main interest was science so I chose two science subjects and one business related subject to keep things interesting.
My subjects were appropriate for my University course except I was required to take Physics in the first year. This was quite challenging not having taken Physics to Leaving Cert but not impossible. I don't think I would do anything differently if I had to repeat the process.
