AS level retake questions

[Jobiii]

I got my AS results for bio, physics, and chemistry and received b's in all of them. I want to sit for all of the exams again in May/June so I have a few questions;
1. Will my old scores be cancelled if I retake in June? So if i receive even lower grades can I change back to my current oct/nov grades?
2. Are there any drawbacks to being a retake student? Or will it not be considered wether or not I retook exams?

Thank You

It's not that ur old marks won't count.
Cie's work is just to help with the examinations.

Then it is upto u whether u want to show ur previous result or new one
I hope u get me.
So don't worry
But only reappear if u r sure u can get an a
Otherwise if u reappear and get a b again
It would very useless and a waste of time.

I suggest you spend more times for a levels
