is that a diploma takes longer as it's worth more credits?

No. Duration is determined by study mode, not credit weight. The Level 7 Diploma in Strategic Management and Leadership Online – MBA Top-Up Route (120 Credits) carries a fixed 120 credits, equivalent to one-third of a UK master’s degree. This credit value is standard for all Level 7 diplomas and does not inherently dictate a longer timeline than other postgraduate modules. Learners choose between a 6-month fast-track or a 9-12 month standard route. The 120 credits are distributed across three 40-credit units. In the fast-track mode, you submit all three assignments concurrently or in rapid succession. In the standard mode, submissions are staggered. The workload intensity differs, but the total credit value remains constant. Therefore, the diploma does not take longer because it is worth more credits; it takes longer only if you select the extended study plan to accommodate professional commitments.
