Hi Krislamb,
Actually you have no choice on MPL or CPL as both pages will lead to the same application pool. KA will allocate you to the respective program that they are dealing with at that moment.
I believe you are in the DA 16 pool rather than MPL. I got a frd receiving call from KA few days ago for DA 16's aptitude test scheduled in early July (if memory serves me right he had the initial test in April).
