Hello Employer. I have read the description of your job and I think, I can do the job quite well without giving any disappointment to you.
I am a B.C.A student and I know better about computers and can work on them quite longer than others. And Also my English is fluent too, that will help in minimizing the errors in the project. I am familiar with ms word, ms Excel, PowerPoint and know how to do work on them in least time.
So you can take my word for the job.
Thanks.
