My son is doing SE and enjoying it. He has AH computer science so isn't finding it too stretching yet but he's thinking of transferring to the Masters if he meets the requirements so that's keeping his motivation up. They were clear at the offer holders day that the CS and SE courses were interchangeable up to 2nd year I think,. Also that there was an opportunity to do the masters at the end of first year subject to some stipulation in relation to test scores and a particular selected option in the 2nd semester. He also had unconditional offers from Glasgow, Dundee and Heriot Watt. Good luck with your application.
