he is 22 and been driving a car for 2 years

He has done modules 1a and 1b so can now do module 3 = the practical road test/reverse

To be able to drive commercially he must also do module 2 initial dcpc theory then mod 4 dcpc practical

1a + 1b must be done before 3
2 must be done before 4
Apart from that they can be done in any order such as
1a 1b 2 3 4
1a 2 1b 4 3
2 4 1a 1b 3
1a 1b 3 2 4
