are payable before you can pay full with additional 20% discounts?

The premise of your question contains a structural contradiction regarding payment mechanics. You cannot pay "before" you pay in full; these are mutually exclusive actions. Typically, institutions offer upfront discounts for full settlement, not additional discounts for paying before the final balance is cleared. For the Level 7 Diploma in Strategic Management and Leadership Online – MBA Top-Up Route (120 Credits), standard practice involves either a full fee payment with a potential early-settlement discount or an instalment plan where the total cost remains fixed or increases slightly to cover administrative overhead. Always verify specific terms with the provider, as discounts are rarely layered on top of instalment agreements.
