Commonly confused with
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ～に加えて is tested against.
vs だけでなく
に加えて simply adds one more item on top, while だけでなく ('not only... but also') emphasizes that the second item is added beyond expectation.
vs うえに
に加えて attaches to nouns and neutrally adds an item, whereas うえに often adds a same-direction (both good or both bad) factor and can follow full clauses.
