Excuse me...
OK, so I don't know what category this goes in, but this was kinda shocking to me and I wanted to see what other people thought of it. I go 5/2 and get an A, but then I go 12/2 and I get a B???????? This ranking system is dumb q.q

99cs in 40 minutes. HOW?
Well, it's based off how others do on that champion around your skill level.
Using your last 3 Zoe games:
G1: 5/2/1 (3.0 KDA) - 162 CS (5.5 CS/Min) - 6 out of 32 Kill Participation (19%) - 12.1k out of 93.3k damage to champions (13% Damage Share) - 3 Wards placed, 0 Pinks bought/placed, 0 wards killed which equated to a 4 Vision score. 2 Turret kills ( which is actually not awful), 6.7k damage to turrets and 0 damage to Drags/Baron.
This isn't a awful game, decent KDA and decent CS/Min for someone at your level, but your vision score, Kill Part, and Damage share are abysmal, while your Turret damage and kills aren't bad but you lack any damage to neutral objectives. Which is why you got a A.
G2: 3/2/8 (5.5 KDA) - 92 CS (2.9 CS/M) - 11/22 KP (26%) - 17.6k/127.8k (14% DS) - 7 WP/1 WD/ 0 CW (14 VS) - 1 TK, 1 IK (Inhib Kill), 6k Turret Damage, 0 Neutral Obj damage.
Great KDA, good Turret Damage, everything else is awful.
G3: 12/2/8 (10 KDA) - 99 CS (2.5 CS/M) - 20/39 KP (50%) - 39k/236.8k (30% DS) - 5 WP/0 WD/ 0 CW (8 VS) - 1 TK, 5k TD, 4.6k NOD
Great KD, KP, DS, Obj damage , awful VS and CS/Min.
The pattern I've noticed is that the system is weighted based on role/champion.
As far as where and when to ward. From mid lane you have a lot of areas to ward to keep safe, specially if you push a lot. Putting Pinks in the river bushes next to mid lane will give you a heads up when a jungler nears and then you just back off, if you don't see them pass in a couple seconds, they are prolly in the mid river entrance bush (the ones on either side of mid the most people ward), Use your Yellow Wards on the opposite side, but usually right between the Mid river entrance bush and the river bush right outside of mid. You can also put them on the exit from red/raptors to rive so you can see when they enter the river. Another good Pink bush is either the bush that leads to the river from the backside of your blue (the one right next to the river bush) and the back of the opponent red bush).
You can also predict jungler ganks and pathing based on information early. If they start blue (red side with bot leash) they will prolly go to Red or Raptors then to Red or Top side Scuttle then they'll try to gank Top or Mid or retreat to Golems or Raptors, so you'd play on the bottom side of Mid lane. Also pay attention to jungle match ups. Rammus vs Graves, Graves red side, means that Rammus will prolly do Red, Raptors, Bot side Scuttle so he'll be able to either gank Mid or Bot or take the round about way to his blue because he won't be able to contest Graves from doing Blue - Red - Top Side Scuttle - Gank or Raptors.

farm, gold per minute, damage per minute, etc. You can't juste have a better KDA and expect a better grade.
It depends on what role your going too ya know
the list that you must be apart of:
KDA- CS- Warding- Objectives-
if you never took out a tower or killed a dragon or baron.. you arent getting a S. 3 deaths is normally acceptable CS .. i have gotten S's with 50-100 cs.. put a ward down.
40 minutes = below 100 cs , 30 minutes = almost 200 cs, wards cs and kda all effect your grade
How long of games? And also, farm on previous game that you got a B? Damage to objectives and vision score? Quite a bit there.
