Clearance #315 is one of sixty six-ball layouts on this site. The white starts on the head spot and you may take the balls in any order; what counts is the number of shots, with each foul adding one.
3 of the six balls lie within 35 cm of a pocket — 1, 2 and 4 — so the first pots are there. The skill is in where the white stops after them. The side pockets are the natural target for ball 1, 2 and 4.
No two balls are touching, so every ball can be played on its own.
Playing with no aiming error, our Expert computer cleared this layout in 7 shots, potting in the order 4 → 3 → 5 → 1 → 2 → 6. 1 of its shots potted nothing: they were position or safety shots to set up an easier pot.
A tidy target is to match the Expert: one shot per ball plus a spare. Keep the white near the middle of the table and the next pot will always be close.
