<p>Back then, it was 2 units, but counted as 4 units of workload for scheduling purposes. So a student back then taking a nominal full time course load of 15 units, but which included 4 workload units of Subject A 1, would only receive 13 units of credit, becoming 2 units “behind”.</p>
<p>At Berkeley, at least, they changed it so that students needing it (now under 10% instead of over 50%) take a special 6 unit version of the first semester English composition course instead of one of the usual 4 unit versions. This also gives full unit credit, unlike the old Subject A 1.</p>
