CSE Physics Optional Strategy
by Abhishek Surana (IAS), AIR-10 in CSE-2017
First of all, I must thank the giant of UPSC Physics preparation – D P Vajpayee sir. He has made it possible that I am writing this blog today. I took coaching for Physics from DIAS in 2014 and appeared for test series in 2016.
Secondly, my sincere gratitude to previous years toppers – Supreet Singh Gulati Sir (2007), Abhijeet Agarwal Sir (2009), Kashish Mittal Sir (2012), Divyanshu Jha Sir (2013), Manish Bansal Sir (2013), Rishav Gupta Sir (2013), Vishu Mahajan (2016) and Prateek Jain (2016). I have immensely benefited from their strategy, notes, and guidance in the past 4 years.
- Mechanics by JC Upadhyay
- Optics by Ghatak
- Electricity and magnetism by Griffith / Satya Prakash
- Thermodynamics by Garg, Bansal, Ghosh
- Resnick and Eisberg
- Quantum Physics by HC Verma
- Atomic and molecular by Rajkumar / Banwell
- Nuclear and Particle by SB Patel
- Solid state Physics by Puri and Babbar
- I came across Hyperphysics very late in my preparation. It is immensely helpful for notes making as well to understand certain concepts. You will find a whole of easy to draw diagrams on this.
- Abhijeet Sir’s notes – available on his blog cited above – use it for in depth study only if you have time.
- Rishav Sir’s notes – available on his blog cited above – They should be your primary source. He has covered almost all the topics succinctly
- Brilliant Tutorial Notes – They are usually available in photocopy form in ORN or Ber Sarai market. They are beneficial to cover previous year questions. Also topics like Solid state and digital electronics can be covered from them
- DIAS classroom notes – If you are not able to attend the classes then get the latest notes from one of the students attending them. All your other notes would be structured around them.
Test series at DIAS
- You must write all the test. And on time
- Many opt for test series by correspondence. I would advice against that. There is no way you can simulate that environment sitting 2000km away. The experience of giving the test series at the centre is very different
Answer writing – This is a highly important part in preparation. You need to practice this well. You can get 50-70% marks for a correct answer (taking into account scaling etc)
- Best way is to prepare model answers for all your tutorial sheets. Get model UPSC answer booklets from market and start writing answers for previous year questions from tutorial sheets. Tutorial Sheet, Previous Year Papers
- Make it a habit to add a line or two in the beginning and end of the answer. This could be related to the physics/definition of the concept asked in the question or a comment on the answer (like for HUP – you can write that such value of answer make it improbable to witness it directly). You can also write real world application for the concept asked or some meta data like who is the discoverer or which experiment led to the discovery of the concept
- Draw diagrams as far as possible.
- Use a different coloured pen (black if you are using blue for writing) for diagrams and underlining
- Be very neat in your presentation. Reduce the cutting
- Most critically, choose the questions carefully. Prepare at least 3 topics out of 4 in each paper thoroughly so that you can attempt 90% paper.
- You can have a look at these model answers by Supreet Sir – Model Answers by Supreet Sir
Notes making – You should ideally take notes in Vajpayee sir class on one side of A4 sheets. Leave the other side blank to add further notes from books or other sources
Revision – Prepare revision notes (summary sheets – 3-4 pages for each units). Cant emphasize the importance of this. If you don’t have these, you’ll be overwhelmed just before the exam by the sheer size of the notes. Have a look at Prateek Jain blog for these flash notes.
I got 303/500 last year and 327/500 this year. On the other hand my preparation last year was much better than this year. But you never know what works in your favour.
All the best!
