Hi S,Pls could you let me know the title, author, and ISBN code of those books?I too would like to explore them but if I wait for my turn to get the books from you, maybe I would have reached my retirement age by then! :-)Another point - I would suggest NOT to depend on the SHL website as the sample questions given there are too easy and low-level. I would go to the extent of saying that they are misguiding candidates. I have first-hand experience of this. The actual tests are far taxing - the questions are too long, too much data to interpret, too less a time (less than a minute for each question), etc.But skill-wise, one won't need a PhD in computational mathematics (whatever that means!). It's basic operators like +, -, x, /, %, etcRegards,A
