when do we apply it?
When ever discussing the motion of any body, like if 3 of 4 values in the formula are given (relating to the motion of a body), u can find the fourth one by the formula!!
You can also use it when discussing motion relating to free fall(or when objects are thrown up into the air), in this case, "a" will be substituted by g(gravity)(value of 10), such that when the body is traveling up into the air , the value will be -10, and when coming down, it will be +10.....

well....idk about sciences fr sure, but last year, my islamiat teacher, who (according him) was the one to make the o/n 2007 islamiat ppr, said that the grade thresholds in gce are fixed (he was refering to islamiat and pk studies at that time) i.e. 90= a* 80=a 70=b and so on
This obviously isnt correct, if this is the case then As and A* would be almost impossible in these two, actually the thresholds for Pak. stud. of 2004 are available

This alone negates him being eligible to be an examiner/paper setter.

I'm pretty sure he's fabricating the former, or talking about setting the internal paper. :p
