Most of the available titles for FMGE & NEET-PG are MCQs based and many freshers with deficient theoretical concepts found them hard to study. Going after standard textbooks for building concepts is often time consuming and frustrating. So the need of a concise title focusing on key theoretical topics (related to FMGE & NEET-PG) was felt since long. I have tried to keep the content to a minimum but had tried to put plenty of the stuff which is important from exam (FMGE & NEET-PG) point of view. For the first edition, I am restricting myself to the most important & commonly asked topics in FMGE & NEET-PG. As I always say, students are the best judge of an authors work. And I personally feel, there is Few more words I always say, “Students are the best judge of an author’s work”. So please send me your feedbacks/ suggestions/ corrections on my Facebook page “DRKAMALKVGROUP”. “To err is human”. Despite my best efforts, some errors must have crept in. I request my dear students to please bear with me. Doing a work of such a large volume, makes room for some errors. Please bring them to my knowledge so that I can upload the corrections on my Facebook page. Also I would correct them in subsequent editions. All the corrections of this title (and my other titles) plus some other exam related information would be updated on my Facebook page “DRKAMALKVGROUP” or on my website “WWW.DRKAMALKVGROUP.CO.IN”. Please follow these and stay updated. Hope this title serves its purpose. Once again thanking all my dear students for showering their blessing on me so far & I hope, this sixth edition would also be greeted with the same enthusiasm.
