Can I only complete certain parts of the MSc or PgC?
Yes. The completion of the work required in each of the areas of study will earn you 15 MSc credits (for all modules covered) or 5/10/15 PgC credits (depending on the module completed). These credits go towards the 180 required for the whole MSc or the 60 required for the whole PgC (respectively). For example, attaining CSTA+ and CSTP+ status earns you 30 MSc credits and 25 PgC credits.
