7/30/2019 Here Are Some Tips to Get 90
1/4
Here are some tips to get 90+ in Physics:
1. Solve the three official CBSE sample papers thoroughly
Doesnt need further explanations, solve them in the 3 hour time frame without looking at the
answers and check with the answers then. See how many marks you get considering step-marking
as well.
You can download these CBSE sample papersfrom here
2. Take time to absorb the marking scheme (Blue-print)
There is a very little chance that the paper comes out of the blue-print like it came in my time but
nonetheless understanding how paper will be set can turn things better for you.
Lets take up the blue-print given by CBSE and Ill explain you how I went about it during my
preparation.
Regular Order
Electrostatics 08 marks
Current electricity 07 marks
Magnetic effect of current and magnetism 08 marks EMI and AC 08 marks
EM Waves 03 marks
Optics 14 marks
Dual nature of radiation and matter 04 marks
Atoms and Nuclei 06 marks
Electronic Devices 07 marks
Communication systems 05 marks
Modified Order (As per weightage)
Optics (Both Wave and Ray optics) Electrostatics
Magnetic effect of current and magnetism
EMI and AC
Current electricity
Electronic devices
Atoms and Nuclei

Communication systems
Dual nature of matter
Electomagnetic waves
As you can see in the second column, I rearranged the topics with the ones having higher weightageon top and so on.
I started from the bottom part. EM waves, saw the chapter for an hour, left it cause I didnt
understand much of it but noted only important definitions like Displacement current, and the wave
equation.
Dual Nature of matter, along with Atoms and Nuclei were finished next. Considering my love for
Atomic Structure (From class XIth), I fairly enjoyed doing this.
Then Communication systems, didnt like the chapter, so left it for later.
Now, there was a little digression here, as I went up the list, the chapters were becoming heavier
and heavier, I had to reshuffle again according to what I knew well. I just stuck to mastering what all
halves I knew and finished them to perfection. Like Electrost atics, Curr ent Electric i ty, Magnetic
effects of cu rrentwere some topics that were there in my mind though not perfectly. I finished them
off from my tuition notes first, did 1 and 2 marker conceptual questions from the sample papers book
and solved some NCERT questions.
Then came EMI and AC. EMI is fairly a theoretical chapter with Lenz law having the maximum
amount of questions floating around. I read its theory from NCERT textbook and solved 1 and 2
markers. Now for EMI, these short questions were quite useful as this chapter has very minute
intricacies which one need to look after.
Alternating Current felt huge, and totally new. I was already weak in Waves and that carried onto
AC as well. I strategized differently for this. Did transformers, generator and their theory, working
and principle really well. I felt these were bigger birds and if they had a chance they would appear as
a five markers.
Then read about Phasors over the Internet, came back and read the chapter again. Felt a little
comfortable and finished it up though not up to the mark. Left it for sometime to settle in my head.
I was now in the final stage with only Optics and few small chapters left. ForRay optics, I read mytuition notes atleast twice. Derivations like forfocus o f mirrors and lens, the lens maker
formulawere done till perfection. Didnt touch a numerical of it till the very last day of my
examination, I felt if I knew the theory I could do the numerical as well. Didnt touch my textbook at
all for Ray optics, only smaller concise notes.
Do study optical instruments, their working and principle as they are almost sure shot every year.

ForWave optics, I read it from the NCERT textbook line by line and to tell you, YDSE(Youngs
Double Slit Experiment) is the most important thing in this chapter. If you had only one day in hand
for it,YDSE, Huygens law and Brewsters angle would be the only thing you would need to do
from this chapter.
With this, Communication systems and Electronic Devices (Semiconductors) were only left.
I somehow mugged up Semiconductors but left Transistors altogether. I knew if they were coming,
they had a higher probability of coming as five markers, and five markers shouldve an option. So, I
am almost safe here.
Communication systems made me yawn first, it made me again. I only studied the definitions of sky
waves, etc., learnt the only formula in the chapter by-heart which is root (2rH) where H is the height
of tower.
3. Underline important lines in textbook while studying
Underlining is important, as when you are done with the chapter, you just have to read the
underlined sentences to get the main gist of the chapter. Boosts your revision really well and saves
time for your girlfriend/boyfriend.
5. Get sample papers, Do them a bit
I personally brought ULike Sample papers for this job. To be frank, I never went past the 1 and 2
markers given in the book. They were plenty in number and I just stuck to those. But avoid doing
this, solve other parts as well. The more pages you do, the more stronger your preparation would be.

If youve plenty of time in hand after this, do the mock test papers.
Also, Consider allotting equal time to all the subjects, if you are acutely short on time, you may skip
doing mock test papers in exam like conditions but just skim through them once.
6. Solve last 10-year question papers
Solving the last 10 year question papers of DELHI region, OUTSIDE DELHI and other regions will
make your 90+ score sure shot. Many of the times, the 1 and 2 markers are direct lifts and you can
see there are many repetitions. By-heart the one markers if you are stuck somewhere.
7. Chillax and enjoy physics
Scoring marks is not the primary goal, read to learn about our beautiful surroundings. Enjoy the
subject, try researching on how physicist thought and deduced the laws and theorems. Then read
your text, youll find yourself enjoying the whole practice and youll get the feeling of reading a novel.
