Time scale for MCSA

Hi ive just passed my 70-270 exam in the last week , I passed my A+ exam 2 years ago (im a slow learner) 
what i want to know is if there is a time frame that all exams should be completed as im thinking of doing the network + plus exam now so that it would go towards my MCSA as an elective
any replys would be appreciated.
