Which IT certificate do you think is the most popular and useful in uk: mcse, mcsd, cisco or oracle?

Go for Cisco AND Oracle, if you are still a student then you should go for both, they are both different courses but together the world opens up (and so does the money) you will be in demand in the big cities like London and your asking wage will be a over �8000 a month you cant go wrong with any IT skills are they are in demand, My son studied both oracle and cisco, it was hard work but worth it, at the end of the Oracle course he took part in a java competition and Oracle in Los Angelas flew a cl of students from the UK to present them with a certificate, if a company will do that for students just think what they will do for their staff.
