Hi Noreen,
I did my NaSENCo at UCL in 2016 and it was the Rita Cheminais book I think. If you have any questions I would email the lecturers and ask they will be able to let you know the core textbooks if you want to buy and read during the summer.
I have attached a document below that gives some really useful strategies for lots of different types of needs which hopefully you’ll find useful!
I also highly recommend finding out each of the deadlines early and planning in a time/place to just focus on your Uni work as it will really help to keep on top of your work/university/life balance!
Lloyd.
