What is "Payback Time?" (Reducing Heat Loss from the home)Watch
The time it takes to pay back the original cost. I buy a set of energy saving lightbulbs, they cost me £40 and save me £5 every year, what is the payback time? The payback time would 40/5 = 8. 8 years is the payback time.
oh right!! thanks man
my revision guide is so vague and its worded horrible
your example helped!!
I've attached a word document with my physics notes for P1. I've got a test on P2a to d
with me, i dont make notes, i dont type or write them i dont feel personally thts the best way of revision, im ver different ahaha
ofc if you find this technique use it
but with me, i revise straight from my revision guide (i'll link the revision guides below) the guide is amazing srs, using my revision guide i got a B in bio and B in chem which i was pretty happy about and that mock was on modules B4,5,6 C4,5,6 which are pretty hard modules tbh harder than modules 1,2,3.
anywhoo, what i do is i read from my revision guide out loud, kinda like teaching myself, and i highlight and annotate my revision guide
if u saw how many annotations i made in my revision guide you'd be surprised at how much ive done, might send you a pic of a page sometime.
i really find reading aloud helpful but ofc if you feel that making notes helps, then by all means DO IT, i may use ur notes for quick revision here nd there but im impressed.
here are the revision guides i DEFINATELY recommend:
i make annotations in these revision guides ^^^^^^
oh and btw if u buy them allotgether then its cheaper than buying seperately
let me kno if u need help
