Well Yeah I didn't prepare that much for Relative Velocity Section because I always found it really confusing and still don't understand many of its concepts! (Even though sooo many teachers taught me this section!!)
And also my teachers told me that Relative Velocity is not even there in the AS n A2 syllabus so i ddnt have to worry much!!
As I am going to do only Math and not Furthur Math for my AS n A2 Hopefully!
Ah, okay...
My teacher had told us it would be the most difficult chapter... And because of that, I'd prepare for it very well.
But unfortunately, relative velocity didn't come out.
Everybody was happy... till the results came out. Those who were expecting a distinction 1 (or A*, as you call it) got a simple A. Cambridge had modified the grade threshold.
