PPL
There is nothing weird with having a restricted PPL as all flying clubs in Singapore only offer this option due to the limited airspace we have. Whether to advance with a PPL in Singapore or Malaysia is totally your call as there are many important factors to consider.
I suggest that you make an effort to look for information outside the forum. It is true that a forum is a place to exchange information, but sometimes you cannot expect people to provide you information from a to z as that will only be termed as "spoonfeeding".
I wish you all the best in your piloting dreams.
