There's no obvious way.
Do more questions. You'll probably get better on the way.
One tip I can tell is,
Trace your hand through the circuit and,
the terminals of the supply connected in the same way to whichever capacitors(positive to left side and negative to right side of all capacitors or vice versa), they will be parallel.
And while tracing, if the right end of a capacitor is connected to the left end of another capacitor, it is in series.
This is not the exact way.
Buy keep this in mind while doing questions.
I'm sure it'll get easier.
