@Slingfox : Question : You have mentioned practising SC daily, what other source you used apart from OG for SC practice ?

And also, could you share your apporach with RC please.

Thanks a ton for the awesome resources!

As few others too have asked, could you please let us know the practice material for SC (apart from OG questions)?

Slingshot this great stuff man,...thank u very much

one doubt - ur notes say that

"the sum of factors of a # is odd, it is not necessarily a perfect square" should be changed to

but I tried the reasoning below

sum of factors of number is of form (a+1)(b+1)(c+1)
if (a+1)(b+1)(c+1)....... = odd
i mean each one must be odd
i.e a+1 is odd
b+1 is odd

so that means
a is even
b is even


which means P1^ a* P2^ b P3^c ......is perfect square?

Whats the flaw here

if a c c are even =>
a=2n b=2m c=2l =>
P1^a * P2^b * P3^c = P1^2n * P2^2m * P3^2l = (P1^n*P1^n) * (P2^m*P2^m) * (P3^l*P3^l) = (P1^n*P2^m*P3^l) * (P1^n*P2^m*P3^l) which is perfect square

Great notes and thanks for sharing.
I was scanning through the Quant notes and did see some typos.
Page 7: 7^3 is 343 and (1+4^4) is 257.

Nice guide. Looking through it I noticed the following:

Quote:
Special Properties of Exponential Expressions Involving 1 or 0
1^n = 1
x^0 = 1 (Exception: 0^0 = Undefined)
0^n = 0 (Exception 0^0 = Undefined)
Show more

Should the exception for 0^n read "0^n is undefined when n is less than or equal to zero)? I would think 0^-1 = 1/0 = undefined (can't divide by zero)

I tried googling but couldn't find an answer.
