About this Assessment
This is Test 9 of the Biology Graduate Level Test Series, and it is the first test of Unit 3 (Microbiology & Immunology). In this complete test series, we have divided the entire biology syllabus into 6 main units, with 4 tests for each unit, making a total of more than 24 tests. This mock test contains 30 highly targeted, B.Sc. standard questions mapped closely to core concepts such as the Immune System, Bacterial Structure, Monoclonal Antibodies, Viral Replication, and Major Histocompatibility Complex (MHC).
This series is very helpful for college graduation exams and government job exams where biology is an important subject, such as Lab Assistant, Forest Department, Animal Husbandry, and Agriculture Department exams. Every test is available in both English and Hindi, and includes different question types like assertion-reason, match-the-following, and statement-based questions to help you prepare well for your exams.
