Having recently talked to the writer myself I got this information:

Current Affairs by Rai Muhammad is a bi monthly digest which contains info of the events of the past two months and info for the jobs currently advertised by the public service commission. It is intended for students appearing in objective type examinations and interviews (of Public Service Commission). For Example his latest edition (Vol. 5) contains: important interview questions for deputy district account officer and deputy accountant. Model papers and past papers for the vacancy of deputy and assistant superintendent jail. It is useful if you have difficulty reading newspaper. You can use it to research topics on the internet.

He is currently working on a CSS digest which will be quarterly and is specially designed for CSS students. He said it should be available in the next month.
Just register on the website of Ilmi and you will get the update when the digest is available.
