They no longer exist, as the system was changed on the wim of some brass who wanted to appear looking busy.
The new "DP" system, which replaced the "QL" system, which replaced the "TQ" system, works like this for the Infantry
NCM DP1 Infantryman = Basic Trade Training
NCM DP2(A) Inf Pl Sp Wpns
NCM DP2(B) Inf Sect 2IC
NCM DP3(A) Inf Sect Comd
NCM DP3(B) Inf Pl 2IC
NCM DP 4 Inf CSM
I‘m assuming that all the old QL4 courses, such as Recce, Comms, Driver, etc, are now classifed as DP2(A)‘s. Can anyone confirm this?
