At the risk of not preaching to the choir and perhaps sounding a bit brutal IMHO despite all the well meaning advice sapperkeeno and V_2 make valid points that are worth considering.
The aptitude test is there for a reason, it is not just a fancy game/filter to be played on the day, to get you onto the course - it is there to see if you have the basic hand eye coordination that is required for flying - something that used to be called old fashioned "stick and rudder" skills and is still very much required, even on modern Fly by wire types.
Such coordination is something that is not just required during basic training, it will be assessed during selection for an airline, after that will frequently be "tested" in your flying career, from on the line, e.g. on every take off or approach and landing with paying passengers down the back, especially in a howling cross wind, and also formally checked in front of an examiner in the simulator every 6 months, right up until you retire.
As an ex trainer I can testify that just like some folks can't drive safely, some people simply cannot fly...there are indeed some who when it comes to coordination do seem to have been "born with two left feet". You can offer advice like others have done on this thread, change teaching techniques, change instructors, but the coordination isn't there....there's no shame in it, and TBF many realised themselves that flying wasn't going to work for them and changed careers.
If confidence is the only issue in the OPs case then just maybe a bit of home practice, perhaps having heeded the hints and tips given by others may well help, but that may not solve an underlying issue. If the coordination isn't there the OP could be setting himself/herself up for a world of expensive pain when they start flying for real. Failing the aptitude test once might be down to bad luck, but failing twice should set the alarm bells ringing. TBH there comes a point (and it might be now, but I'd certainly suggest after a third failure) where maybe it is time to consider saving money and doing something else.
In any event I wish the OP good luck.
