ABSTRACT:
A tilted board made to hold reading material to study for increasing clarity. It helps to maintain order among papers, especially when more than one reference material needs to be observed. It allows limited writing possibilities like changing or underlining words, making notes etc. When the board's surface is treated with the necessary material, it permits one to write on it by chalk or marking pen.
