As you can see above, the criteria listed states an 'OR' option and not 'AND' so it should not matter. Then again this are just minimum requirements...In the event of stiff competition then prehaps what you say might be true....Then again we would not know how SIA carry out it's selection process...
Hopefully some senior bro can shed some light here....
