Hi,
it's really not that difficult, just time consuming.
For every learning outcome/ objective you have to write a little paragraph on why you feel/ know, you have met it. Every statement needs to be cross-referenced to a piece of evidence, which you will need to submit, too.
A piece of evidence can be used for several objectives.
Evidence is everything that has been countersigned by a e.g. manager or senior therapist.
Please do take the advise by Oscar. Just recently, a successful registration applicant has written a huge thread on what he has done. Lots of good information in that one!
Good luck,
cheers,
Fyzzio
