PREFACETarget’s ‘NEET: Chemistry PSP (Previous Solved Papers)’ is a compilation of questions asked in the past 32years (2019-1988) in the National Eligibility cum Entrance Test (NEET), formerly known as the All IndiaPre-Medical Test (AIPMT). The book is crafted in accordance with the Std. XI and Std. XII NCERT textbook.The book consists of topic - wise categorization of questions. Each chapter is further segregated intosubtopics and thereafter all the questions pertaining to a subtopic are arranged year-wise starting with thelatest year. To aid students, we have also provided hints for questions wherever deemed necessary.TENTA graphical (% wise) analysis of the subtopics for the past 32 years as well as 7 years(2013 onwards) has been provided at the onset of every topic. Both the graphs will help the students tounderstand and analyse each subtopic’s distribution for AIPMT (32 years) and NEET-UG (7 Years).We are confident that this book will comprehensively cater to needs of students and effectively assist themto achieve their goal.We welcome readers’ comments and suggestions which will enable us to refine and enrich this book further.All the best to all Aspirants!Yours faithfully,AuthorsEdition: FirstNFrequently Asked Questions MPLEWhy the needfor twographs? COWhy thisbook?This book acts as a go-to tool to find all the AIPMT/NEET questions since the past 32 years atone place. The subtopic wise arrangement of questions provides the break-down of a chapter into itsimportant components which will enable students to design an effective learning plan. The graphical analysis guides students in ascertaining their own preparation of a particulartopic.Admission for undergraduate and post graduate medical courses underwent a critical changewith the introduction of NEET in 2013. Although it received a huge backlash and was criticisedfor the following two years, NEET went on to replace AIPMT in 2016. The introduction ofNEET brought in a few structural differences in terms of how the exam was conducted.Although the syllabus has majorly remained the same, the chances of asking a question from aparticular subtopic is seen to vary slightly with the inception of NEET.The two graphs will fundamentally help the students to understand that the (weightage)distribution of a particular topic can vary i.e., a particular subtopic having the most weightagefor AIPMT may not necessarily be the subtopic with the most weightage for NEET. The two graphs provide a subtopic’s weightage distribution over the past 32 years (for AIPMT)and over the past 7 years (for NEET-UG). The students can use these graphs as a self-evaluation tool by analyzing and comparing aparticular subtopic’s weightage with their preparation of the subtopic. This exercise wouldhelp the students to get a clear picture about their strength and weakness based on thesubtopics. Students can also use the graphs as a source to know the most important as well as leastimportant subtopics as per weightage of a particular topic which will further help them inplanning the study structure of a particular chapter.(Note: The percentage-wise weightage analysis of subtopics is solely for the knowledge ofstudents and does not guarantee questions from subtopics having the most weightage, in thefuture exams.Question classification of a subtopic is done as per the authors’ discretion and may varywith respect to another individual.)SAHow are thetwo graphsbeneficial tothe students?DisclaimerUtmost care has been taken in compiling and checking the information to ensure that the content is useful and accurate.
