(1) What is the major difference between mcsd and mcad, and which one is better? (2) What is the quickest method of learning the material and building the skills required to pass the mcsd/mcad? And have the majority of people who have adopted this method earned their qualifications? (3) Where can i get past exam papers for free (or for a very cheap price)? (4) How much does it cost in total to get the qualification i.e. how much does it cost to buy the neccessary training and exam-preparation material and plus what is the cost of taking the actual exam? Please reply ASAP as I am thinking about starting to study straight away and i'm running out of time. Thank you very much. Moshrul Hussain.
