UCL MSc Finance

Hello, I will start MSc Finance at UCL in September, and am looking for advice on how best to prepare for the quantitative modules (quantitative methods, financial econometrics, time series analysis and advanced quantitative finance). Are there particular prep books/study material that anyone would recommend? I am a mature student myself working in finance and it's been a decade since I took any modules in quantitative subjects.

Also, are there websites that can give reviews of the teaching staff, and where I might be able to purchase class notes and books from students who have/are taking this course?

I'd also welcome any opportunity to meet with students who have taken (or are currently taking) this course.

Thank you
