On the ILS, if it's going to be radar vectored, immediately request "further vectoring/repositioning" if you foresee things are going too fast for you ex. you still haven't finished all the checks.. or when you are being vectored for a straight-in ILS from high altitude/flight level which means the speed control and/or configuring the aircraft may be a bit more challenging while descending with the G/S.
Broadly speaking, do some mental rehearsal of the whole profile... Chunk down the trip and manage each section separately until it's done then move to the next section... Don't overwhelm yourself by thinking about how much blood and sweat it's going to take over the period of the test to pass the whole thing.
ex. Focus no further than the Departure section...get it done...
then the next step is the En-route section....get it done...
Joining/Initial Approach...Done..
Precision/Non-precision...done..
EFATO...done......
etc.....bit by bit..
