Z - Ze same side (in a french accent ). The two CH3 groups aren't on the same side so I'd say E-isomer.
That's not how E/Z assignments work, you need to look at the two heaviest atoms joined to the double bond first. So the two heaviest (first) atoms are chlorine and carbon which are on zee zame zide

I was scrolling down this thread despairing at the lack of knowledge of the rules of Messrs Cahn, Ingold and Prelog. Your post saved what remains of my sanity. Eternal thanks.
However, if we rank the groups attached to the two central carbon atoms we get
12__17 __C=C 1___12
Therefore, the highest ranks are on the same side which SHOULD make them Z isomers BUT THEY ARE NOT
Please xplain
IGNORE the _
Listen to EVS, and not the others. If the mark scheme for said question says that the molecule you showed us is the E isomer, it is wrong and was written by idiots.
