All the best to those taking A levels as a private student! Been through it before and honestly it hurts physically and mentally especially when you have to work at the same time.
And if you ever feel like retaking is not suitable for you, there are always other options out there such as taking a private degree or if you are rich enough you can study overseas.
Honestly, private degrees are not as bad as i thought. Many of my peers went on to work in well respected companies with decent pay. Those articles you see in the newspapers are not a 100% true reflection of private universities.
