I don't like noob techies who are into IT for the money.

My friend is jealous of me and he wants to get to my level. I told him that he should take Oracle certifications if he wants a good chance to a raise or a promotion (at least, it's a well-respected series of certs and everyone I know who took them got serious salary increases and respect from their managers).
For example, I studied for 12 weeks, for 12 hours per day for the OCA. He thinks he can just quickly cram a cert in three days and get big money. Nope.

This guy failed Network+ countless times. I remember he wanted to quickly get his CCNA when he barely understands how folders work.

The level of foolishness is amazing..
Yeah, anyway..

So, here is the worst experience, not one.. but recent two of many of the encounters I had with my OOP teacher... (I am in Second Year of Engineering). Lets Call him T.
To give a background of T... He knows nothing but acts like he is the master... you'll get to know this...

Incident #0:
*me developing a website for a client and T just bumps in*
T: Hey, what are you upto.
M:Nothing sir, just some Web-dev stuff.
T: What languages do you use?
M: I am currently using embedded ruby.
T: No no, I meant, what languages do you use for web-dev?
*inner* M: Ok, try to act stupid... He is not worth of all the knowledge.
M: Sorry sir, I just use simple HTML-CSS.
T: Ohh, I use Wordpress... It's a great language to build websites.
*inner* M: He has no idea what WP really is, he is a fuckshit.
T: It's so simple and easy, that you code for Desktop view, press Ctrl-M and then it automatically makes it for mobile view.
*inner* M: Bursts out into laughter
M: OK sir, will look over it.

Incident #1:
*He is teaching, suddenly topic comes of Oracle Certification for Java*
T: I know many of you have idea about java, but do you have what it takes to be an OCJP..
*inner* M: LOL...
T: It is a really hard thing, and I can bet... I can bet *he did repeat that twice* that no one from you can even qualify OCJP.
*inner* M: It's time... It's time
M: Excuse me sir, first of all it's OCA... OCJP does not exist anymore... And secondly, I am an OCA...
*inner* M: Yeah... Fuck you bitch!
*assucimg inner* T:Fuck, asshole..$#@#%@!@$@%#

And whole class was like -> o.O

Can't stop laughing

Hi guys! I got an opportunity in one of the biggest consulting/strategy companies in the world, however I need to write the OCA and OCP Java exams to get in. The OCA is in about a month + 2-3 weeks and OCP towards the end of the year. I kinda know Java but the exams seem to be hard. May you please guide/advise on how I can get over this mountain :)? Anything that worked for you? Or did not work?

Anyone have the OCA , any tips is it worth having ?
