How do i achieve sub-15?

  • Make sure that you always plan all of your cross in inspection and that you aren't looking at it when you solve it.
  • Make sure you know full OLL and PLL, including dot cases, N perms and G perms.
  • You don't need algs for every F2L case, but if you feel that there are any that you solve very inefficiently, use J Perm's F2L PDF to find a better alg.
  • Try to start implementing lookahead if you can - it shouldn't matter too much if you can't solve every case without looking, but if you ever get one that you're particularly comfortable with, try to track pieces for your next pair.
  • Do lots of slow solves to find out where you are going wrong and to implement these techniques.
  • Also do normal solves so that you will actually know what you are averaging.

Targeted practise.
Record some of your solves and watch them and try figure out what you need to practise.

Unless you’re me (I’m sub 15 without full OLL). I still recommend learning full OLL though.
Thx :) i’ll try to implement those tips

Something that helped me break through a plateau around your level was splitting my times by step before deciding what to practise. Do a few Ao12s and note roughly where the time goes — for sub-15, cross around 2s, F2L around 8-9s and last layer around 4s is a decent shape to aim for. Whichever step is furthest over its target is the one to drill that week, instead of trying to fix everything at once.

For lookahead, the drill that actually moved the needle for me was a short block of untimed solves where the only rule is no pausing: turn as slowly as you need to, but never stop turning while you track the next pair. It feels really slow at first, but that's the point — timed solves mostly just reinforce the pauses.

One more thing: pick one thing to count for a week, like how many crosses you fully planned in inspection, or how many F2L pairs you solved without a rotation. When the average isn't moving, seeing that number climb is what keeps you going. Sub-15 is closer than it feels from sub-20 — good luck!
