Busy Busy & Busy !!!!!!!

Argh!!! Next week will be a busiest week for me because I'm going to have 3 presentations ( ENG presentation, IOM presentation and FOA presentation ). Besides that, I'm also having 2 coursework test ( ITS and ME ) on next week. Plus today and tomorrow I need to prepare and attend for my beloved cousin sister's wedding. How am I going to manage my time to practise for my presentations and also revision for that 2 tests??? I really don't understand what the lecturer taught us during the lectures. I'm dying larr....please pray hard that I can die peacefully..SWT!!!!
