the left $C$ and $C$, capacitors are in parallel to the add up to equivalent of $2 C$
now, this $2 \mathrm{C}$ is in series with the left middle $2 \mathrm{C}$ so, it will add up to Ceq of $\mathrm{C} \ldots$
again this $\mathrm{C}$ is parallel with middle centre $\mathrm{C},$ adding up to $2 \mathrm{C}$
now again, this $2 \mathrm{C}$ is in series with the left upper $2 \mathrm{C}$ so, it will add up to Ceq of $\mathrm{C} \ldots$
and finally this $C$ is in parallel with $2 C$
so, the final $\operatorname{ceq}$ is $C+2 C=3 C$
