,Welcome
Dear ECS1601 students,
Welcome to the Together We Pass family, and I hope you find the resources in this study notes useful.
My name is Brilliant Maisiri, and I am lecturing in a range of study groups in 2017, with my
specialisation being in Economics and Accounting.
I have a Bsc Honours in Administration, and I am a member in Chartsec (International Accounting
Board). I worked as a tutor while I was at university, and as full time lecturer I a private college since
2015. I currently work as a lecturer at Skills Academy for the Accounting School.
I have been working with Together We Pass study groups for a number of years, and am pleased to be
assisting with a number of study groups this term. These study notes have been created for my
students in my study groups, as well as for anyone needing some extra help with AUE2601.
If you need additional assistance, please remember you can join my study group at any time to get help
from me directly.
Kind regards
