Educational institutes often underestimate the true cost of custom exam platform development. While initial estimates seem manageable, hidden costs quickly escalate, leading to budget overruns and project failures. This article reveals the hidden costs that catch institutes off guard.

The Initial Estimate Trap

What Institutes See

Initial Custom Development Estimate:

What They Actually Pay

Actual Custom Development Costs:

  • Development: $300,000 - $500,000 (100% overrun)
