Math book for sci,comerce,arts ? Tell ur suggestn |
|
Answer» Rd Sharma and NCERT will be sufficient for boards Best is NCERT for basics and Other Can be RS Aggarwal for extra imp. Questions on each chapter or other than RS you can purchase RD Sharma for extra questions. Remember that in exams all the extra questions are important on these books, i.e., RS or RD. You have to do extra questions to get 100% or if you are not touching any one of the RD or RS and your knowledge is based till NCERT only then don\'t hope for even 85% marks as by doing only NCERT you can achieve only 60 to 70% and not more than that. But NCERT is important as well so do NCERT firstly to clear your basics and then RS or RD. Good Luck.??? |
