That moment when the instructor is explaining array in Java, and you are the only one in the batch having 4 Years of Experience, and Certification by Oracle

Just 1 step.

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

Quick Java question.

Does spending £200 on Oracle certification raise your job market value?
Or is it just a pointless money maker for Oracle.

Should I get the oracle certified associate certification? I just took a Java class in college that apparently prepares me for it. But it's $245...

I got word that the Oracle Java certification exam is pretty cheap to take for the next four weeks ($25 as opposed to almost ten times that). What's the chance that a junior dev working currently with Java (aka me) can learn enough from the official Java certification course in the evenings until then and pass the exam?

Should I take the Oracle Certified Associate exam on Java 8? I just finished an intro course in college that apparently covers all the topics. It's $245 though.
