ANNA UNIVERSITY,CHENNAI
PAPER VALUATION REPORT MAY/JUNE 2012
BE/BTECH FOURTH,SIXTH SEMESTERS
IN ADDITION WITH 3RD,5TH,7TH SEMESTERS

HOW ABOUT THE PAPER CORRECTION/VALUATION FOR  FOURTH,SIXTH SEMESTERS BE/BTECH ANNA UNIVERSITY MAY/JUNE 2012 EXAMINATIONS

Fourth,sixth semester paper valuation is currently going on and valuation is excepted to complete by Next Week , and May/June/July 2012 Anna University Results(Common To All Colleges in TN) are expected to announce by last week of July 2012 or first week of August 2012 ([Except Eight Semester],[ Including Second Semester]) - Sources Added

So What About The Paper Valuation Is It Liberal Or Strict ?
------------------------------------------------------------------------
First Of All Nobody can Predict Any Paper Evaluation history . Its Purely depends on the examiner , if you are really lucky your paper May passes with liberal valuation

We Will Update The Detail Whatever We gathered  Instantly Keep Visiting our Rejinpaul.com for More Updated Details : PREM,ADMIN

4TH SEMESTER CSE &IT:
                                      "4th Semester Operating Systems and Microprocessor and micro controller  For CSE Department Students got Some Tough Question Paper Earlier, Results are not Up To The Mark for Operating system and MM  in comparing with other 4th semester CSE subjects"


PQT Results Will Be Good When Compared To PRP


--------------------------------------------------------
SQEA For 2nd Year IT Students Will Probably Get Max. Grace Marks As 14 If they Attended The Following questions
