Oasc hints tips and time distance examples


#1

If anyone can assist in any hints tips for oasc and a variety of time and distance sample questions it would be appreciated.


#2

There are numerous books available, such as this one.


#3

There’s a huge thread in the armed forces careers section on The Student Room


#4

The exercises in the OASC prep booklet on BADER is a good place to start, however, they are a bit more complex during the actual thing! The scenarios being more complex, not the maths.

The maths is basic DST.


#5

I always remember speed = distance / time (not really sure why, but that’s the format that sticks).

Think of the units - meters per second (distance per time) - and make sure they match.


#6

The planning exercises from these books really helped me prepare, much more so than just practicing speed distance time calculations.


#7

The trick really is to work out a system that works for you, and practise it.

Recognising the sub-divisions is probably the biggest part, and how they fit together.

Eg learn:

2 mph = 30 min/mi
3 mph = 20 m/m
4 mph = 15 m/m
5 mph = 12 m/m
6 mph = 10 m/m
7.5 mph = 8 m/m

And vice-versa (eg 12 mph = 5m/m)

From there you can also do *10 or /10, 100, etc - eg 60 mph = 1 m/m

Recognising those figures will probably stand you in good stead for any SDT calculations you’ll need to make.
