Cpale review

Genuine question po, enrolled in CPALE rev center, paid for DP only, which is half of the total review cost because i want to check muna if kaya kong pasukan talaga since im a working reviewee. After 6-8 classes decided to defer and not continue nalang muna. Pwede bang hindi na bayaran ang remaining balance ko?

Like sa mga schools na if hindi makakabayad, di na makaka attend ng classes? Or im still obliged for full payment?
