3. using plist..?

Any suggestions and ideas would be greatly appreciated.

Store the data in application with any way. But it depends on size of data.

If you store large data, then Sqlite is the best way.

For Sqlite,

You need to use Core Data with an SQLite persistent store. Core Data excels at handling both size and complexity in data models. See my answer to a similar question for details

There is a learning curve to Core Data but once you understand it, it makes writing complex apps very easy.

Finally i decide to use HTML to load questions into uiwebview and sqlite for storing answers.
