Name is. And welcome to Puneel's world, friends. Hello. Welcome to this amazing platform of
Defencewala. My name is Mohit Puneia and I am your mathematics mentor. Many of you know me, many
of you don't know me. Mohit Puneia here and welcome to Puneia's world. This is our line which we
generally use in our welcome. Today, we're going to talk about our first lecture of our power batch, NDA
batch, of mathematics. You all know, mathematics is very important. Mathematics is made of 300 marks.
And generally, 60 to 70 questions, 120 questions, 60 to 70 question attempt, after doing 60 to 70
question, we try to take it bad. 120 question, 60 to 70 questions, attempt can make it bad. Let's call it a
good attempt. But we have to do more than that, then only we will go up from the rest of the people.
Today, we will study math, son. In math, you have a practice the requirement is. I agree, you guys agree
with you. You agree with me. That's why in less time, we will focus on more questions. And how will you
do the questions? Time is limited, limited? Yes, it's very limited.
But you will get a practice sheet after each chapter. You'll get a practice sheet in which you have to try to
answer maximum questions from previous year. If you don't have to try that. If you have questions, then
we will give you the video solution which you will find on the app. Download the app and go to the Shackti
Batch. You'll find the power batch only there. Go to the Math section and you'll have, when you click the
Math section, you will find the notes of this class and you will find a practice sheet with 35 questions for
sets chapter and 35 questions you will tempt. The next day, you'll get the video solution will be available.
But here I'd like to tell you a small point. First, note s as much as you want to make during the lecture.
Keep it short notes. It's not that you first watch the lecture first, then make notes after that. We don't have
that much time because our paper is in November, so we have to save time. We have to focus on our
speed, on our accuracy, rather than that we watch a lecture over and again.
I would say that whenever you watch the lecture, watch the lecture and try to answer the questions. The
questions you are attempting, it's a very good thing. What you did not do, you should watch the video
solution. The video solution doesn't have to be watched completely. If you have 35 questions and you
have not answered five questions, number wise, let's say you have not answered the 20th question, you
should go directly to the 20th question did not happen, then directly go to the 20th question and look at
the solution and check where you were making a mistake. What you missed, which you did not answer
that question. In the same way, you will be able to increase your speed and you will be able to save your
time and you will be able to practice more. So today, we will complete the sets chapter. And what will be
our pattern? First, we will complete the whole theory of sets which, from your NDA exam point of view, is
very important from the point of view of your NDA exam. And then after that, we will do the questions.
See, set chapter and relation and function chapters are there.
Generally, every year, 10 to 12 questions are asked. Every year, every year, 12 to 13 questions are
asked. So you, 10 to 13, 14, such questions are always different. It's not a fixed pattern that 12 questions
will come. From 10 to 12 to 13 questions, you will be asked from these three chapters set, relation, and
function. Now, why am I talking about these three chapters? Because these three chapters are very much
linked to each other. Without sets, there cannot be a relation, relation and function, and without relation,
there cannot be function. So we will do these three chapters together. First set, then relation, then
functions. Okay? So total questions, 10 to 12 questions, you'll be ready this week. This week, you'll be
