They are not 'triple A levels' - they are BTEC Extended Diplomas and T levels and these are not 'the same' as A levels.
They are vocational qualifcaitions and designed for those aiming at employment and apprenticeships.
if you want to do Engineering or another technology subject at a sensible Uni you will need A levels - in particular Maths and Physics.
These two A levels with a BTEC Extended Certficate in another technology subject is usually okay - most Uni will accept this.
T Levels are not accepted in any form by many Universites - they are not academic qualitifcations, they are to prepare students for apprenticeships and other trade courses at college.
You need to work out what you want to do after Sixth Form / College - if you do the 'wrong' qualifications at this stage it will greatly restrict what you are able to do at 18.
