I am a Img it's been more than 10 yrs since my graduation, so do I need to do the prerequisites again .I see for science course there is no time limit does it mean i need not do prerequisites on Anatomy,physiology,microbiology?what does that mean and what are considered science subjects .Can anybody please tell how much does it cost to do prerequisites in Tcc ,or community colleges.Do they have online or weekend classes at Tarrant county college.Any information is helpful .Thank you for your time.
