Ive posted this a bit earlier, on the queries board...without any luck.
Anyways Edexcel's alternative to practical for AS physics is coming up, and i'd like all or any instructions about this paper including the practicals to study and the main topics to revise and focus on...
Hopefully this board may help me out.
Thanks in advance.

I don't do edexcel.
Maybe the dude or tq can help you out.

Hey, welcome to the forum.
I hate to bring you bad news, but the honest truth is that the number of ppqs are very limited for the new alternative to practical paper.
You can try practicing the IGCSE alternative to practical paper for physics.
All topics come up to be absolutely honest with you. But the most common ones are mechanics and waves.

Thank you for replying so early.
It seems the new syllabus is causing quite the frustration, my exam is in a few days, and my school isnt actually a good source of information when it comes to practical work...come to think of it,during the entire year we haven't entered the lab to do an experiment, ever...though the resources are available.
So you understand my concern...and the situation i'm in.
Additionally I'd like to know how exactly i would benefit from revising O-level papers...it seems there is very little relationship between it and AS.

Also may someone upload the alternative to practical past papers? ???

Have you tried freeexampapers.com ?
