I purchased oswaal 15 sample paper book mathematics class 12 2020 from Flipkart. When I opened the book, I found everything was ok, and the book was in a good condition. But now when I am practising it, when I compared the book with the book of my other friends, it doesn't contain some question and has many wrong questions in it. Also some questions were not from our present syllabus. Was this information helpful? |
