I do share your predicaments during OE and I do feel too that perhaps, you have not been well briefed or rather appropriately briefed on the OE and its expectation.
Like previously, it is paramount that one gets the proper view and preparation from the correct source rather than from the negative-iris!
Some ladies made it through on the B737 and now they are on the B744. It is preparations and never luck!
I am almost into my second decade and have assisted many, getting through their OE.
I do wish all the best, Sir!!!
