3 Preface SSC Question Paper Set is a penultimate weapon, designed to facilitate thorough preparation for the students appearing for the SSC Board Examination. The book includes 15 Model Questions Papers across three subjects Solved Question Papers and 2 Practice Question Papers for each subject. These Question Papers are in tune with the changed syllabus and are prepared based on the latest paper pattern. Additionally, 12 Board Question Papers (2015 and 2016) have been included to gear up the students for the Examination. The Model Answer Papers offer complete answers for every question with the relevant marking scheme to make sure the students encounter no scope for error. Solutions to Board Question Papers of 2015 and 2016 examinations are available in downloadable PDF format at our website The purpose behind this is to make students familiar with the current question paper pattern and marking schemes. It also gives them a holistic understanding of the exact nature of the board question papers. As the old adage goes, Practice makes a man Perfect, students will find here, a goldmine of Question Papers to practice, before they are up for their final battle. We are sure these Question Papers will prove to be extremely instrumental in achieving monumental scores in the Board Examinations. The journey to create a complete book is strewn with triumphs, failures and near misses. If you think we ve nearly missed something or want to applaud us for our triumphs, we d love to hear from you. A book affects eternity; one can never tell where its influence stops. We wish the students all the best for their examinations. Yours faithfully, Publisher.
