What are the important topics for Science & Tech? Please comment what you feel! 

- Nuclear treaty and nuclear Energy

- Biotech (Gene editing, GM crop, RNA, DNA, embryo twinning)

- Space related ( Perseverance, Chandrayaan, Debris)

- IT (5g, AI, Quantum, Blockchain, data security related)

- Health - VAccine

-Energy( geothermal, Hydrogen gas, fuel cells, solar )


For space, I feel UPSC is not focusing on 'smaller' missions like going to Mars and Moon. It's going for more 'exotic' missions like e-LISA which is a Gravitational wave observatory just like LIGO which was asked couple of years ago. So, that maybe narrows down a little bit.


also Large Hadron Collider and wo International proj jisme Fusion reactor banaane ki koshish kar rhe....forgetting the name

ITER

Test series ka favrt question!

@SergioRamos attempt atleast 55, if you want to stay in the race. Speaking from previous experiences, i am from non science background, but lot of questions seems difficult prima facie only, give them a good read and you can easily do 55+ in csat.


Will do so. thanks! :)

@D503 so your method is wrong?


He just used the scale once. You can use the big scale ( 7.5* 6 times= 24 cm) and the small scale (3.25 * 7 times=23.75cm) the difference gives 0.25 basically this is HCF only, much simpler to understand this way.

Guys, what is the optimum number of CSAT questions to be attempted? 

Is 45-50 good or low? (considering I will attempt all the passages)

Bro quant reasoning zyada kro passage me subjectivity rhti, kyu pange lene hai upsc se :p

Then this 7 Cr question is also important which was asked previously in one of UPSC exam probably (APFC 2016)

What was the title of the thesis that Dr BR Ambedkar submitted to the London School of Economics for which he was awarded his doctorate in 1923?
