CSC PAPER ON 5TH NOVEMBER AT BMSCE
Hello frnd csc visited BMSCE on 5/11/2008. it started wit ppt. criteria 60%
agg in engg (B.E).Aptitude paper was different for circuit branches (ECE,CS,TE,EE)
and non circuit branches. This is all about circuit branches apti paper. No
negative markings in apti. It has one apti paper(40 ques in 40 min) one tech
paper includes c, c++, dbms, microprocessor 8085,microcontrorller(75 ques in
45 min, all 75 ques repeated so plz learn tech ques frm previous year
papers).Aptitude also most of them r repeated ques so learn from previous
papers and learn following topics from rs agarwal.
percentage.
average.
LR ques.etc.
it will be simple and try answering 20 out of 40 correctly. u wil surely get
through.

ans well apti and tech, u will get through apti. and then the rest of the
process is easy. they just see your confidence level. In BMSCE 29 got
through apti out of which 22 got selected in tech round. ALL 22 were
selected. so HR is for just namesake.
ALL THE BEST. KEEP FAITH IN GOD. U WILL BE SELECTED. those who don't get
selected don't worry, there is always better job waiting for you. |
