Could any one suggest 1 or 2 subjects to start ICWAI

Hi Friends,

I am graduated in mathematics and Computer science. I am currently working as software Engineer, I am interested in doing ICWAI . Since I am completely new to this stream. Before taking any postal coaching I want to study at home for 1 month. I don’t want to waste money at this moment , instead I want start studying 2 subjects and see how things works for me. Could any of suggest me one or two papers to start with, How should I study ? What is effective way I should do my exercises? Every week I want to dedicate around 15 hours for studying ICWAI. Thanks Bharadwaj.
