SUM of the total in GroupBy

Question

This is query that I'm running to group the category
SELECT cs.category as category,COUNT(*) AS total_cand
FROM candidate_session cs
WHERE cs.year = 2006
and cs.month = 'November'
and cs.category in ('DIPLOMA','RETAKE','CERTIFICATION')
GROUP BY csd.category
O/P
Category Count
DIPLOMA 100
RETAKE 200
CERTIFICATION 1100
Is there any way that the count can be sum-ed to give the total (1400) in the same query.Thanks.
