As every operator has its own rule, it cannot be commented upon what has been set in place for your outfit.
It should be documented in your Part-B (or equivalent) what configuration order is to be used by crew. Using improved climb (IC) prior to bleeds off makes total sense as you get airborne with a normal air-conditioning system configuration, not one that requires reconfiguring adding to workload that could be avoided.
(There are outfits that always use Bleeds Off performance and reconfigure as part of their SOPs and After Takeoff Checklist, those airlines have optimised their takeoff weight in all cases, saving a bit of fuel on the takeoff and allow crew to assume as normal as this is their normal departure technique, they will subsequently also use Bleed Off IC if the need dictates...)
Unless your instructor can point out where in your manual such requirements for configuration are described, I would say it's up to you.
