who joined this group about a week ago... my name is David, i'm 17
from Ohio/USA, and learned how to solve a rubik's cube (using a
cheat-sheet for algs) on Christmas (although I had my cube before
then). I did 12 in a row today to find my average time, which is 2:41
at the moment.

RUR' and RU'R'. Do those to your cube and learn how an why they work.
That is the goal state for each corner/edge pair. Play around with
the cube trying to transform each case that comes up into one of
those, ready for insertion.

The last step (orienting edges again) is completely unnecessary. But
other than that, yes, it's a good method. Using this, you can achieve
times in the 16's. Many people will tell you that orienting corners
before permuting them is better because it leads into learning PLL.
Keeping the order this way leads better into COLL. It's all a matter
of preference.
> Third question: are there any algs to rotate 1 corner (i know that
it would also have to move edges, b/c it's not possible to rotate just
one piece) What about rotate 2 adjacent corners, or 2 opposite
corners? I currently have one alg, which rotates all of the corners
except front left; it is inefficient and I sometimes have to execute
it as many as 5 times to orient all of the corners.
You cannot rotate a single corner. You also cannot flip a lone edge.
Twisting them and shuffling them around are completely separate. You
can have one without the other quite easily. Also, if you learn how
to perform the mirror of the alg you know (L'U'LU'L'U2L compared to
RUR'URU2R') you can complete any possible orientation in two algs.
Learning shorter algs for a couple of cases is helpful and simple.
They're really just extensions of the basic alg you already know.
> Fourth question -- any other general tips on getting faster?
Learn why the things you do to the cube work the way they do. It
makes recalling things so much easier during solves. Stay calm, and
go slowly. But most importantly, have fun.
