Ýou got to wait another 2 more weeks before receiving another
letter from LTA, inside, there will be another letter for Medical
Checkup.
Bring that letter to the nearest Polyclinic. Xrays is also
needed. The final cost should be around $44.70.. 
. (that was the amount I paid in June 2011,
when I apply for PHVL).
Can go SATA clinics also. .. I think i only pay 30+ for the check
up. They have their rates stated in their websites. Polyclinics
queue is just too long for me thuo sata also must queur but still
faster la hehe
