CSWP sample exam- Equation Problem

Hello everyone!

I am trying to prepare for CSWP CORE exam and I was trying to work on the sample that is available from SW.

All is fine expect I am encountering a problem with the equation. I have created a bunch of global variables, but when I try to update each of them for answering a new question it simply takes a lot of time.

I am not re-building automatically, but as soon as I enter a value inside a global variable, it takes a lot to update.

I am concerned about this since I think it may make minutes run out during the real exam. Has anyone suggestions for improving this?

Here there are the equations I am using.

"A"=213

"D1@Sketch2"="A"

"B"=200

"D2@Sketch2"="B"

"C"= 170

"D1@Sketch4"="C"

"D2@Sketch4"="C"

"X@Sketch7"="A"/3

"D"=130

"D2@Boss-Extrude4"  = "D" - 10

"E"=41

"D1@Sketch8"="E"

"D1@Cut-Extrude2"  = "D"

"D1@Sketch9"="B"/3 +10mm

"D2@Boss-Extrude5" = "D" - 10

"D1@Sketch10"="E"

"D1@Cut-Extrude3"  = "D"
