With the hold pool, one either needs to complete the full integrated course, to the required standard, which will mean one enters the main CTC holdpool (I think this is now the flexicrew hold pool-the names have changed a bit since I went through, but the structure is similar). The other way in is to complete AQC with CTC (their version of MCC/JOC). This gets one into a slightly different hold pool, as integrated cadets have priority. However, cadets from both pools are, I believe, getting placements with easyJet without too much delay. Just doing groundschool won't do it, as one wouldn't have completed any flying with CTC.
