Ingeni NEET Biology Course provides the students with updated concepts along with extended exposure to contemporary areas of the subject. The course also aims at emphasizing the underlying principles that are common to animals, plants and microorganisms as well as highlighting the relationship of Biology with other areas of knowledge. The format of the course allows a simple, clear, sequential flow of concepts. It relates the study of biology to real life through the use of technology. It links the discoveries and innovations in biology to everyday life such as environment, industry, health and agriculture. The updated course focuses on understanding and application of scientific principles while ensuring that ample opportunities and scope for learning and appreciating basic concepts continue to be available within its framework. The broad aims of the curriculum are:
It is expected that the students would get exposure to various branches of Biology in the course more contextually and systematically as they study its various units.

About the Instructor

About the Instructor

I am Dr Tushar Dash , Phd in Biotechnology from IIT Delhi working as a freelancer home tutor since 2011. These 9 years of home tutoring has evolved a different personality in me towards handling the variety of subjects ranging from class I to class X of all boards. i teach biology exclusively with orientation towards cracking NEET for 11th and 12th class. I also have an expertise in handling the students studying IB and IGCSE curricula. I make my students very strong and innovative from the very grassroots level of the subjects. In this process of mentoring the basic concepts are clarified to crystal clarity and the fear factor is also removed. I also teach them not to fall into laid traps in the questions from different scenarios. I also motivate them when they couldn’t meet their parent’s expectations. The exam blues and memory blues are very well tackled by me by giving them secret weapons to use during the time of need.
