This is awesome book for study

It is very gud book

misprinted book of the year award goes to this SBS book .... without answer key u can't get sured about wether u have got the answer or not ...but in this book answer key is not present even answers are also not there in mathematics. which is the most dissapointed.... other then it's bad quality...it is somewhat helpful ...not somewhat but very much helpful if you are preparing chapterwise...but for practice I will suggest ten year...
