<p>You can call the office of the registrar and ask but if you really struggles during CompSci A, then you will probably most likely struggle in upper level CompSci classes too. So my advice would be to retake CompSci A (dunno what its name is under ISIS; not a CompSci major) at JHU first semester especially since first semester is covered grades. This way, you will establish a great foundation and can add onto that once you take upper level classes.</p>
