AIPMT All India Pre Medical Test is conducted by CBSE in compliance with the directives of the Hon'ble Supreme Court of India for admissions to 15% seats of Medical/ Dental colleges of India. Some other State Govt university or institutions also use AIPMT merit list for admission in the Medical Colleges/Dental Colleges against seats under their control. Here we have published model test paper for Biology for practice purpose with objective type MCQs multiple choice questions based on AIPMT previous years question papers.
