personal advice lang from exp. comptia a+ bears no weight in the IT industry, trust me. If you want entry level certs better get network+ ,
security+, ccna, or microsoft entry level certs. unang una pangit advancement ng certs offered by comptia especially a+, second, yung mga topics covered sa a+ mostly alam mo na dapat yan if you are a 4 year it releated course graduate. just my 2 cents. To answer your question, yes multiple choice sya na pwede balikan yung mga naunang question, unlike other exams na pag tapos na sa isang question d na pwede balikan,
