In physics practical
28 marks
Is it easy to get
It's not easy to get 28 marks
30 marks
Is it easy to get
I will say this
OK
So
OK
Let's see
Whose comments are coming
Sir
Tomorrow is my practical.
So
If your practical
You know what you have to do.

They will definitely give the FAS.
OK
The titration will be fixed.
Sir
My practical is over.
It was very easy yesterday.
Copied
And give
Hey, Aditya, you're just copying and pasting. This is wrong, you know.
You shouldn't copy it
Sir Byayoji's
Budgetary
Okay
We
Sir Physics Practicals
I
Okay, it was neck.
Physics Practicals
Sir, tomorrow
Sir, your college
How much is it? How much does it cost?
Mumbai-Pune? No, in Palghar.
Sir, home
What is GR board?
In practicals, teachers get 27 marks
Give, no, no
There's nothing like that for giving marks to teachers
They are not compulsory; you haven't done the practicals either.
So Marx will become a bit difficult to meet.
Sir Biology's hair, Bharati Jandal's with
With Kyoshins
Tell me, please, sir, teachers
Don't ask anything at all
Bal Bharti's
Anything at all
Do I have to write a project?
You are not in biology
Writing projections is extremely important.
You will get stuck in the problem anyway.
22 likes are coming, please do it
Get it up to 50, just take a look at all of them
86 people are watching, so 22 likes are a bit low
I will do it only during the practical exam.
Then it becomes your duty.
You will have to do it.
A little support will also be needed for this teacher.
I don't keep getting likes from you, I keep getting them from others.
Trial or understand
Sir, you are the moderator.
I am the moderator here, and I also check the papers.
Alright
What are the practicals in C.B.S.E. Chemistry?
I will ask you, the title will come.
And Salt Anlisis will come.
Sir Practical
Do it
The project will arrive.
You showed me
Need
Sir, my name is...
Subhangi
Sir Khel Practical
Circle Practical
Please tell me the search for CBSC, please
It was just now, the practical sir of C B S C
Please provide the viva questions for both physics and chemistry practicals.
Please also ask some teachers
Ales
So, I can see many children here, I'm noticing
Mostly in the practicals of Chemistry and Physics
There are very few doubts or reservations, that's correct.
Sir, I live in Palgar.
So, you must also know about Palgar, sir.
You don't know
And all the children will know it.
What happens
You don't know
You can tell me these things clearly
Third option, not that you sometimes argue with him
Ask about CBR
What is the full form of CBR?
Constant burette reading is taken
Ask about the Ind Point how it is with you
Pilot reading
As the examiner keeps setting the reading difficulty level for you
As in reading set 12.4
And if you write Ladha 12.4, you will get 3 marks there.
Whoever has as many marks as possible
But if you brought the Jagapé from version 12.4
12.3 or 12.5
One went up above 12.4 and one went down below 12.4
You will still get full marks.
But after 12.4, two up and two down occurred, then it started marking one by one.
There's a slight dark color appearing.
So, you know, mistakes can happen there.
Sir, in practicals, everyone gets 30 out of 30 marks, right? Please let us know.
This is not possible.
It's not possible to give everyone 30 out of 30.
You understand what I'm saying
That's not possible.
Give it, both of you give it
I don't feel there's any problem.
You're watching 92 children
38 people liked it
That's great for me, that's fine
Sir, not everyone gets 39 in practicals, not everyone gets it.
Many children have problems.
Because he couldn't provide that answer there
I'm just looking right here
Like if you're experiencing meter bridge
He is looking at the child.
Ask him/her
Oh yes, man, the issue with the child's leg was a case of congenital clubfoot.
First, become practical. Okay, I'll become practical.
Surf please, fun video of those physics practicals.
Surf Please Electronics One also provides a practical cup.
Please tell me the hundred group zero to fifth mark.
Okay, a child has a doubt. Explain how group zero to fifth works.
In group analysis, if you encounter a problem or salt, first perform zero group analysis.
Add OS and Enavesh to it, heat it up, and place the paper on top.
In group analysis, if you encounter a problem or a salt, first perform zero group analysis, heat it, and then place a paper over it.
Next, place the OS enavesh, place the enavesh, heat it, and then place the paper on top.
I've already provided the address; it's currently a salt analysis.
Sir, please look at Electronics One and its practicals; if I find any teacher, I'll definitely get him to teach it.
Sir, do you know anything about the board question? Please tell me.
Of course, I'll tell you, my friend.
Sir, you are also an examiner.
Yes, I am also an examiner.
I keep going to colleges in Mumbai.
What questions are asked in the chemistry quiz by Sir Vibha?
Just tell me the chemistry quiz.
Just told you already.
Please don't practice the parallel method, sir.
This stupid thing, how long will the videos keep coming?
I'm forgetting the practical on the parallax method.
Alright.
I will soon try my best to get that done for you.
Fifty likes have been received.
Alright.
Sir, please electronics.
And look, so many comments will come, comments upon comments, arriving today.
I'm seeing so many comments.
That you're doing 30 out of 30 just to look at it.
NAMESH...
Namesake.
I give 30 out of 30 to the student.
It's not that I don't give it.
But they all want everything to be perfect.
Only then do I give it.
I give them up to 29-28.
I give the maximum to all children,
Because I don't want to cut their marks, okay.
Do they also ask questions from the book in Sir Chemisty Viva?
If ever, at some point, you are unable to properly answer the viva questions,
Even just a little bit of attention on books, please.
What is the formula of picric acid?
Just ask one reaction, casually, like that.
Sir,
My practicals are on Thursday.
The physics vivavoce through
But I had tried.
I have written 90% of the things correctly in the seat.
You don't need head writings in science.
In science, you don't get head writing, kid, okay.
You have written correctly, so you will get it.
Sir, is there cheating in chemistry practicals?
It depends on your college.
Are they cheating or not?
If I were in your college, I'd definitely check in with you first.
You're crying so much, aren't you?
Sir, please watch your assembly language lectures.
But nothing comes.
Watch lectures on assembly, assembly language.
I don't understand assembly language.
It hasn't come to me yet, okay.

That's Maharashtra Board, the State Board's,
Then, when I receive the letters from there,
Then it will be decided by that college.
Where will I go?
How to determine the Katanas and Anayans?
Performing salt analysis at the time.
I can find out from the color.
When did the practicals start in Zoom meetings, dude?
I don't know about the Zoom meeting.
What are you saying?

Okay, okay,
Alright, I did post a video,
I can't understand you.
I'm telling you, sir, please upload one more video for the kids.
Sir, I've watched the video.
But I get a little confused sometimes,
Why do you get confused, man, Harsh?
Sir is very nervous.
The nervous one, the goods,

Study hard, alright,
For Class 12 Chemistry Practicals,
You have to write the process.
No, not all experiments.
You don't have to write a processor.
The bus stop is just to write.
And in physics,
If precaution is taken,
So, precautions need to be written.
A child is speaking.
Teach me the functional group,
for the functional group,
But I've made so many videos, man.
So why aren't functional groups being taught?
Why aren't you writing?
But learning it is very easy.
Why are you staying so long?
In chemistry, you also need to write the theory.
Theory is not in the midst of
Where should I write the theory in Chemistry?
I'll tell you.
If you are experiencing tinnitus,
So, a small theory needs to be written in it.
I'll also tell you what to write in that theory.
The FAS you prepare, whether 0.1 mol or 0.5 mol
So how do you prepare?
Just write down those calculations.
Don't do anything else.
For salt analysis, you need a table
Prepare
Even the ketone's ketone's ketone's test shouldn't be done
You have applied nail polish or similar substance at home.
How are you?
If you're sampling something, smell it.
You know, the blood order comes, so just understand it
In the ketone test
You need to add anios
And administer a solution of sodium nitroprusside
So if red color PPT comes, blood color comes, okay, it comes out quite nicely.
So understand, PPT won't come, color will come
So understand that you have a ketone group.
So, do you understand, in Baramati, Pune district, the same old one
Pour in the nitro benzene, brother

My soul is so under-attentive, I don't even know why.
It doesn't move, it's stuck in one place because of the children.
Doesn't support it, nor can we do anything for the children either.
Whoever likes it will do it, won't they? Not even Salt when giving it.
They find it difficult to identify radicals because of understanding.

Your videos are very good thanks to the scanner
Just look at them—what will they give me, and what won't they give me?
I don't even think about the best of the best.
I think that if my scanner has been used by him, then it has helped the children, which is fine.
