What works did you put in your LTCL programme?
Observing the syllabus, I find some of the LTCL pieces are technically more challenging than some of the FTCL ones.
Nonetheless, technical aspect is just one part. The musical and communication parts would definitely be seriously evaluated, too.
The approval rate of FTCL is not high, but I suspect it is not single digit % as one may think.
Furthermore, if you have a good teacher, then you'd likely have a much more comfortable time to prepare.
You need not to make up a balanced programme for FTCL. A specialised or thematic onemay also work.
Good luck.
