I can't seen to find a way to get below 25 units lost in this challenge.
In first part of the challenge I lose around 9-10 units.
Second part is pretty ok, I lost 3-4 units there, but in 3rd part I lose around 10-15 units every time. Mostly I lose zealots to siege tank in the very last part of the challenge.
Do you have any tips for this challenge.
EDIT: Path of Ascension is protos challenge, where you need to chose type of units to counter 3 different enemy groups.

For the last part I used hallucinations along with the shield to help protect from incoming tank fire. I found it helped to split the forces above and below, making sure the zealots charged the tanks.
For the hallucination, try and make the tanks splash their own units
