Only info we get from our instrument is the bank angle.
Let's hope you don't have an access to a real aircraft. You can't see rate of turn anywhere else rather than attitude indicator (bank)? Please inform your IRE to have yours and his licence revoked. Did you ever consider that the rate of turn is just what the phrase says:
rate of
turn - just look at the DG/HSI/ND/compass and note for how many degrees the heading changes in 3 seconds and then if you divide the heading change by 3 you get rate of turn. Yeah, I know, I should get a Nobel prize for this

And what did you do during IR course studies? Walk around with shiny one-bar eppauletes instead of reading PANS OPS? Did you ever fly an IFR procedure (let's say base turn) designed for Cat D aircraft with a 100kt spamcan and adjust the turn accordingly? Or you just use "standard" bank and then wonder why those idiots create procedures, which lead you into severe undershoot every single time, even if you ace the turn?
All IFR procedures, designed according to PANS OPS require rate of turn 3°/s or 25° bank - whichever is less. The main reason why jets don't have a turn coordinator is because usually the speed during instrument procedures are so high that the 25° bank is limiting - for a 3°/s turn you would need a bank higher than 25°.
