About the books :- With an expanding curriculum, even primary school children have to cope with heavy, over-stuffed schoolbags. Holy Faith International took a fresh look at this weighty problem and came up with a light but ingenious solution: a set of All-in-One textbooks catering to the SEMESTER-WISE needs of children. What easier way to reduce the weight of a child's schoolbag, than to combine all the core textbooks within a single cover. Two semester-wise textbooks per class. No more heavy bags, no more aching backs! Yet no textual matter has been excluded, nor has any compromise been made on quality! Yet again Holy faith international keeps its promise to deliver economical, world-class, state-of-the-art books to meet every kind of educational need.
