How much is baby engaged?

I’m nearly 36 weeks and went to see the midwife this morning due to experiencing period like cramps and she said baby’s head is ‘ well engaged’ and is so low and that is the reason why I’ve been feeling a lot of pain. However on my notes she has written 3/5 palpable, to me 3/5 doesn’t seem very engaged and still has to drop a lot further yet?
