For people starting Higher Computing for the first time this year, I recommend the Scholar website Here .
I also recommend the Leckie & Leckie past papers as they give you a clear idea of the level of knowledge required for your exam.
The course it split up into two compulsory units and one optional unit:
- Unit 1 - The Software Development Process
- Unit 2 - Computer Systems
- Unit 3* - Artificial Intelligence/Computing Networking/Computer Programming/Multimedia Technology
I found the course very enjoyable and very informative. I've found out much more about how the 'insides' of the computer work.
If you feel you want to discuss anything remotely connected to Higher Computing then feel free, and this topic isn't only for people studying computing this year, people who have already studied it feel free to post!
