Timings are just as usual college timings. From 9 am to 5 pm. We get up at 8 am and reach home/hostel/PG at 6 pm. Saturday might be holiday depending on the batch you are allotted. But mostly classes are shifted from Saturdays( Its a half day). There are various gaps in between and also mass bunks are an option. You can enjoy your college life easily, and being in college forms an integral part of college life.
Studies are mostly done on a day before exams, if you are not over-enthusiastic about them.

No. No college offers 100% placement. Not even IIT's. There are students who don't want to get placed, as they want to study further. The college guarantees that even if you are half decent in your studies, you will be surely placed. So yeah, its about 100%. But it depends on you as well.
