AP Inter Model Papers

Intermediate students require good practice of model papers before they get ready for IPE 2013. Here is Botany Model Question Paper 2 for Senior Intermediate students. Students can practice these papers for the practice and assess themselves. Maximum marks for the paper 2 is 60 and duration of the exam is 3 hours.
