One really important thing for these newly graduated pilots to do is maintain proficiency. At their experience level proficiency will deteriorate very quickly from lack of practice. To keep their licenses current, they need to fly at least 12 hours in the 12 months preceding expiry.
That can be expensive and very often leads to unacceptable practices. Falsification of certificates of flying time is the most common. The crocodiles at the CAAP can smell these from a mile away because it's always the same operators who issue the fake documents. Then it's feeding time at CAAP.
Renting airplanes is not cheap. But it is often the only way to keep current legally. A Cessna 172 pilot could split the cost of rental four ways among friends to make this more affordable. Note that there is only one place in the Philippines where they can rent airplanes. Those guys and gals who want to do this need to speak with BHG or MG about this.
