Seems like your salary after emplacement is quite similar to a fresh grad's. Though your promotions after that are, of course, way faster than a graduate joining the service in 2014 would have been.

Based on the figures provided it seems like doing the part-time degree and emplacement have been beneficial. I do wonder though now that they've unified the pay scales (with diploma holders starting lower on the same scale, rather than having different tracks entirely) how the typical progression for a diploma holder would be.
