Are NCERT Books Appropriate For JEE Preparation?

To answer this in one word, yes! NCERT books are perfect for preparing for the Joint Entrance Examinations as most of the syllabus is based on CBSE 11th and 12th Standard topics. Ex-JEE candidates widely recommend it as the pattern of CBSE exams, and the National Entrance Exams for admission to colleges are very similar. NCERT books are also preferred by many students who are, at the moment, preparing for JEE Mains 2021.

As it happens, the type of questions that appear in Central Board exams has similarity to the ones which appear in JEE. Due to this similarity in pattern and type of question, most students like to stick to the NCERT books. Therefore, without a doubt, these books can be used as a perfect reference to study for the entrance exams. 

Certain students who belong to other state boards or the ISC board might find it difficult to follow the pattern of NCERT books. Even students from the CBSE board itself might find it sometimes challenging to understand all concepts from a single book. These students can absolutely rely upon other preparatory books for entrance exams. 

How Can You Take Help From NCERT Books For JEE Preparation?

Understand the Basics

Read and understand the basic concepts of Physics, Chemistry, and Mathematics well from the NCERT textbooks to build a strong foundation. A strong base in all the subjects will help you lead to studying more complex concepts in higher studies. It goes without saying that NCERT books can be your strong suit in understanding the ground concepts. Comprehending the basics well is the key to preparing for the entrance exams and what concepts are to arrive during graduation in your desired engineering college. 

Know in Detail

All the topics and concepts of Physics, Chemistry, and Mathematics are explained in detail in the NCERT textbooks. In-depth information about all the topics is provided in the books for students to clear all their doubts and learn better. 

Often, students are left hanging when there are no examples provided for certain theories and formulas, and that can stay as incomplete information in the student’s minds. To avoid any such situations, the books contain proper explanations and examples for each and every concept and theory for the convenience of the students. 

Solved Solutions

Solutions for NCERT books of 11th and 12th standard are available online in abundance. If you are stuck on any maths problem, you can get a pdf or some other version where you will find the solved solution. For the easy accessibility of solved solutions, NCERT books are considered the greatest choice for entrance exam preparation. 

NCERT Solutions for Class 11 Maths is something that every student needs to learn for the mathematics part in the JEE Mains. Along with the Class 11 Maths Solutions, having NCERT Solutions for Class 12 Maths will be like a cherry on top for those who are looking to score high in the entrance exams. Solved solutions are a delight for students who have already understood the concepts and are left with questionnaires to solve. 

Reappearing Questions

It has been observed in the past couple of years that the questions that appeared for JEE Chemistry Exam from the inorganic section have been directly extracted from the NCERT books. The questions are the same as the NCERT textbooks, not only for Chemistry but also for Physics and Mathematics. This goes on to show how preparing from the NCERT books can be beneficial for you as most of the questions come from these books. 

Why Go For Other Options?

The textbooks published by NCERT (National Council of Educational Research and Training) are essential as they comprise the whole syllabus of the 11th and 12th standard and the JEE Exam pattern. However, in the recent past, many experts have argued that NCERT books are not enough for appearing in JEE Exams. 

Most experts have come to this aggressive conclusion because consulting multiple books can help students learn all the concepts better. Apart from that, consulting the same book that is explained by a different author allows the students to have different perspectives on the same area of concern. 

Some of the other books widely recommended by experts around the country are:

  • Concepts of Physics by H.C. Verma (Vol. I & II)
  • Understanding Physics by the authors’ Freedman and Young
  • Organic Chemistry by O.P. Tandon
  • P Bahadur’s Concept of Physical Chemistry
  • R.D. Sharma’s Objective Mathematics
  • Amit M Agarwal’s Integral Calculus

Frequently Asked Questions

Q1. Are books other than NCERT Solutions necessary?

Answer: NCERT books and their solutions are necessary when the JEE preparations are considered. These books are required to form the base knowledge and learn about each and every concept in the book. You can also use other preparatory books for JEE, mentioned here previously.

Precision Optics in Medicine

Medicine continues to advance as time moves forward, and as it does, the tools used also become more precise. One of the big advancements has been in stereotactic radiation. The application got more accurate, and the radiation doses pinpoint the exact place it needs to go. 

That accuracy makes sure less normal tissue gets damaged. The new technology uses 3-dimensional radiotherapy planning. 

Some people have never heard of eye melanoma. That type of cancer sometimes gets treated with radiotherapy. The treatment doesn’t cause pain but needs precision so that it saves the patient’s vision

People compare getting radiation to how it feels when they get X-rays. They don’t feel pain, but they know they are getting doses of radiation. A precision optics corporation can help hospitals treat cancer in a pain-free setting. 

Military and Precision Optics

Our military system depends on the use of cutting-edge, high-precision optics. When these perform missions in the dark, they need light detection systems to show them where there are potential threats. The tools they use contain lightweight lenses made from optical devices. 

Precision optical transceivers get used in monitoring various environments. The systems that get used rely on optimized sight and surveillance equipment. Those tools use precision optics to work. 

Heads-up displays get used for showing information in the person’s field of view. That makes it easy for the user not to have to look away. These devices were designed for the military but have become used for commercial aircraft and automobiles as well. 

When the military performs aerial operations, they use telescope systems. These scopes get used for viewing oncoming threats that are long distances away. Those could be missiles, approaching ships, and vehicles. 

Detection and avoidance make traveling safe. Precision optics get used for avoiding terrorist threats. Enemy missiles get detected by heat and then deflected away by patterns of lasers. 

Other military-grade equipment, like optical sites on guns, help protect soldiers during battle. Being precise can make the difference between life and death. As we learn more about precision optics, we see how important they have become. 

That is why the government has turned toward technology even more in the past decade. They need innovative solutions to stay ahead of the game when it comes to security and defense. Precision optical groups offer proven results in the most challenging environments.

Expanding Your Child’s Education Through Life Skills



Do not underestimate your child’s abilities. Your child can learn a lot of life skills that will contribute to a well-rounded education like math skills, taking challenging online test like impossible quiz and weekly quiz. At the end of the day, the lessons he/she will learn now will bring him/her to great success very soon. Here are a few things you can do to ensure that your child will gain many opportunities to grow as a student and person.

Give Them Their Own Bank Account

Your middle school child is old enough to have and to manage their own bank account. Start them off with a small amount of money that they are able to invest, and give them the opportunity to save and take charge of their own finances. Encourage them to deposit their own money from that point on, and remind them to keep track of how much interest they earn. It will certainly be a learning experience for them that will start them off on the road to future savings.

Volunteering Opportunities

No one is too young to volunteer. Everyone has an ability, and every ability can be used for the purpose of helping others. Volunteering exposes your child to a variety of situations and many different people.

Whether your child plays piano in a senior care home or walks dogs at a local pet shop, volunteering will help them decide what they may want to do later in life. It also gives your child a sense of responsibility and reminds them that their presence is important in the world, along with teaching the life skills of being on time and being dependable.

Home Business

Your child doesn’t have to have a large home business in order to learn valuable skills through it. Even a simple paper route gives your child the opportunity to put their education into real-life practice. Delivering papers on time, collecting money from the customers on the route, and counting the total of money earned is a great education for any child in lessons of math, people skills and responsibility.

The Ethical Struggles in “The Three-Body Problem” Novel




The Chinese fiction novelThe Three-Body Problem has become a hit right after its first publication. It is a trilogy containing The Three-Body Problem, The Dark Forest and Death’s End. Because of the books’ attractive and imaginative plots,its writer Liu Cixin won many awards and even became the first Asian writer to win the Hugo-Award. After fighting over the right to film the novel for a long time, it is going to be adapted into an original series by Netfilx. The popularity of this novel is so amazing that makes us feel bewildered. Why is it so popular? From the characters, we can find out the reason immediately.

In the first novel of this trilogy, Ye Wenjie who was born in a highly-educated family plays a key role in it. She is trapped in a precarious situation during China’s Cultural Revolution. Ye was at first an innocent student who gradually becomes a callous and cruel researcher determined to betray the whole human race. Her ethical transformation is nothing short of impressive and we cannot deny this novel’s attraction. In the book, we can see that she was hesitant to make a decision at first and then her ethical struggle faded away as time passed by. Here are two stages that may account for her attitude transformation.

Stage One: Faith is Lost in the Turmoil

Due to the inflicting period in China’s Cultural Revolution, Ye Wenjie was forced to work in the rural area after her father was tortured to death. One day she was forced to sign her name on a document, which was used to frame other people for the wrongdoing. However, when Ye turned down the request, the cadre Cheng changed her gentle voice into a furious action and poured a bucket of cold water onto Ye. At that time, Ye gradually lost her faith in benevolent humanity. She didn’t know what to believe and whom she should believe in. She was totally at a loss.

Stage Two: Loyalty to Herself but Betrayal to the Whole World

            When she worked for the government agency called the Red Coast Base Ye found out a way to transmit messages to the outer space. Instinctively, she sent a message to the outside world and happened to receive the signal from the distant planet of Trisolaris. Her colleague noticed her intention and was about to snitch on her. Then she set up a trap and killed both the colleague and her husband. She achieved her goal and did not feel guilty about it at all. But what Ye did was a total betrayal to the whole world.

For Ye, this was justifiable because she wanted to carry out her new plan-that is to let other more civilized aliens to take charge of the whole human race. But for most of us, her deed is unforgivable ethically and morally. Using the most advanced techniques to take revenge on the whole world is unbelievable and immoral. However, on the other hand, we also feel pity for Ye’s experience. At last, we will find ourselves in a dilemma. The novel is fascinating as it touches upon many controversial topics and characters. The reader will find a true self in this novel and enjoy the sparks of thought during reading!
