Revise Regularly:

To get the proper benefits of studying and practicing one should keep revising at regular intervals. This will help in the memorizing. Candidates should make it a point to revise the entire syllabus several times before the exams so as to be thorough with each concept included in each topic. When one student do regular revision, one can keep the track of the progress of the study

Unit-1:Kingdom Animalia

Introduction:

Animal kingdom comprise of multicellular eukaryotic animals and is one of the kingdoms among five kingdom schemes of classification. There is a distinction in form and type of various animals; there are a few important characteristics that are regular to different organisms. Every one organisms of the Animal kingdom are multicellular still they don’t display the same example of cell organization. Organ frameworks in various animal groups display different examples of complexities. Categorization of animals can be done on the premise of the symmetry of their body. The course of action of body parts around a main line or point decides the symmetry.

Unit-2: Tissues And Types Of Tissues

Introduction:

The higher plants have highly complex bodies made up of different types of cells. All cells are made up of different types of cells. All cells are of same origin but afterwards they get differentiated into different types of cells. Cells of similar shape and size constitute a group which perform diverse functions. A group of cells performing a particular function is collectively called as tissue. A tissue may be defined as “a group of similar or dissimilar cells having common origin and performing a specific function”.

Chapter Analysis:

​Questions from Tissues have appeared frequently in the question papers. Except for the year 2017, 2015 and 2013, every year had at least one question appearing from this chapter. A total of 18 questions have been asked from this chapter in the last 11 years, with the last year holding 3 questions. Thus, we can conclude that this is a medium weightage chapter and it will be wise to expect atleast 1 question from this chapter in the coming papers.

Unit-7: Microbes in Human Welfare

Introduction:

Microbes are beneficial as well as detrimental to the welfare of human beings. Microbes are utilized in many ways for human beings. These microscopic organisms produce half the oxygen in the world. Many types of fungus and other microbes release enzymes that digest dead stuff. They are more than half of the living biomass on the planet. In human body, 9 out of 10 cells are microbes. Microbes are everywhere on our body, in homes, far below the earth’s surface and up to the atmosphere, in cold, cool, warm and hot and very hot places, and even in places without oxygen. Microorganisms always live in water. They can eat all sorts of things, including oil, rocks, dead and living plants and animals.

Chapter Analysis:

The pattern in the number of questions asked in NEET from Microbes is a really uneven one and there have been regular rise and fall in the number of questions asked. All in all, a total of 27 questions have been asked in the past 11 years. However, the last year saw an abrupt increase in the number of questions being asked with 6 questions. Also, in the year of 2012, an enormous 7 questions were asked. However, on other side, the number of questions in the other years have remained 3, limiting to 0 in 2015 and 2009. Hence, making a wild guess, we can estimate 2-3 question being asked in the years to follow.
The following bar-graph depicts the variation of number of questions being asked:



The important topics to cover in Microbes are:
• Microbes in Household
• Microbes in Sewage Treatment
• Microbes used in production of Biogas and Biofertilizers

Tips and Tricks:

Since there has been irregularity in the number of questions appearing in the paper from Microbes, it is best to keep this chapter to your strength as this chapter can be the deal-breaker in one of the years to follow. The following points might help the students in putting this chapter in their good books:
1. Reading NCERT is must for this topic. Here is the link to NCERT PDF version of the topic:
2. Making Flash Cards will be beneficial as this chapter will not require much revision as students must have been well versed in this topic from their early days.
3. The past year questions must be solved along with the questions available at the end of the chapter in NCERT.
4. The summary given at the end of NCERT must be given proper reading.
5. Practice a large number of questions from this topic and leave no stones unturned to make this chapter one of your strengths.
