1、Dear Mark，

It's a pity that you can’t go over your lessons with us．The final exam will be held next Thursday，which is also the last day of the exam week．What is different about the exam is that it consists of only two parts，that is，answering three of the five questions and writing articles．We are supposed to go over our mid term exam papers，textbooks and class notes to prepare for it．The grade is made up of three parts．The final exam takes up 55%，the research work takes up 20% and the mid term grade accounts for 25% of it．

Please feel free to contact if you are still not clear about it．

Hope you will recover soon and also get a satisfactory mark in the exam．
