A bit of study into how temp, altitude and pressure change with relation to eachother will be useful.
Some work on converting Knots to 'miles per minute' again is going to assist. Eg, 420 Knots os 7 miles per minute, if there is closing between 2 aircraft of 60 knots, that is one mile every minute and so on. Do some work on the halves and thirds etc as well.
Have a gooogle for True Airspeed (TAS), Ground Speed (GS) and Indiicated Airspeed (IAS) and how they relate to what an aircraft does speeds wise at altitudes and in winds.
This should get you started and probably see you through the first 6 weeks with a little leg up.
