We all know that Medicine, Surgery & Obstetrics-Gynecology are extremely important subjects for exams. During early phase of preparation, when students have plenty of time, they can study these subjects in full details but as the exam approaches near and when they face time-crunch, they are not able to revise these big subjects effectively. This was the thought behind bringing this title so that students can revise these bulky subjects in little less time and can go the examination hall with that much needed confidence. I have tried to compile high yield topics with relevant illustrations so that student can remember the content for a longer period. As I always say, students are the best judge of an author’s work. In addition, I personally feel, there is always enough room left for further improvement. Therefore, I expect my dear students to share their valuable feedbacks regarding betterment of subsequent editions. Despite my best efforts, some errors must have crept in. Since I have typed the entire content myself, I expect a few spelling mistakes. I request dear readers, to share the same with me (on the channels mentioned below).
