Hello,

There are many private sites who provide soft copy of question papers like a2zpapers, brpaper, indiaguess.

visit their sites or search for it in the browser. You will get many sites page ranked in your screen. You can choose anyone and go through it.

More than question paper go through book examples, summary, end chapter questions. try to read chapters as much as you can. take time and read it line by line. it will help you remember the content.

Hope it helps!
