Me too! still at MCs. I am not starting WA either. Good Luck! 20 days to go!

You might want to take a shot at some WAs. The concepts are the same as MC but WA is more in depth.

Default MC Passing

Does anyone know what you should be shooting for on the MC so your written answer gets graded?

It's usually 12/20. Spring 2017 was the exception, only requiring 10/20.

I vouch for Parker 1000000%. He does fantastic work and expertly communicates.

Yeh, you should really be giving him a raise CA.

Yeah I was totally unprepared and took MLC in Spring 2018..got 11/20. WA wasn't even graded, although even if it were I would have maybe gotten a couple points.

When you have a fund whose contributions increase at rate g, and the contributions grow at rate r, what formula is best to find the accumulation value after n years?

the geometric series for the AV looks like this:

[(1+ r)^20] + [1+g]*[(1 + r)^19] + ... + [(1 + g)^19]*[1 + r] + [(1 + g)^20]

If you factor out either (1 + r)^20 or (1 + g)^20 you get a geometric series with ratio either (1 + g) / (1 + r) or (1 + r) / (1 + g) multiplied by what you factored out. Then you recall that 1 + x + x^2 + ... + x^20 = (x^21 - 1) / (x - 1) unless x = 1, in which case the sum is just 21.

Ah, this is the explanation I needed. Thank you!
