Download CBSE Class XII Projects

By on Dec 20, 2008 in On A Whim | 180 comments

It’s that time of the year when in schools across the country teachers have started pestering students to submit their class 12th Board practical projects. Since I need to do a few good deeds before Christmas, I decided to put my computer science and chemistry projects. OK, not completely mine. Naman made a major portion of the computer project; as for chemistry, I never really did that one – simply ‘slurped’ off projects from others, smacked on my own formatting to make it looks loads cooler than their Comic Sans riff-raff, and submitted the thing somewhere around the very last days before the practicals. CBSE Class 12 Computer Science Project (ZIP, ~619 KB): In the root folder of the archive you’ll find my ‘quizzing software’ (named Jabberwocky). Included is the source code for the text-only and ‘graphics’ version of the software (using graphics.h). I suggest people to show the former, because if you’re unable to answer questions about the Turbo C++ graphics library you’re screwed. I also included the project report cover and body (needed along with the project when you submit it) as a demo on what is to be written. However, I did not include editable versions since, well, you’ve the source code anyway. Also included is the final end-user package of the software which contains a library of quiz questions with the software can use. In the folder Rach’s Project, you’ll find…Rach’s project. I had no role to play in the making of that except for putting it up here. Contrary to popular belief, Rach says that he was not jacking off when creating the project (this rumor started because of the filenames he used). He says it’s because he’s a big fan of Jack Sparrow. CBSE Class 12 Chemistry Project (ZIP, ~131 KB): I’ve included DOC and ODT versions of three different computer projects. The one on conductivity was what I eventually submitted. The one on rayon fibres is Rach’s. Hope people find this useful. There are some other older posts of mine too which you may find useful. Organic Chemistry Test Flowchart Chemistry Salt Analysis Cheatsheet (mobile version of the same for viewing on cellphones): A perennial favorite. After all, salt analysis is a bitch when it comes to chemistry practicals. I hear that students in loads of schools are using this. I also heard that in our school the teachers themselves are distributing this to the students. (I think I should ask my ‘share’ from the school, out of the money it collects from the students for ‘study material’.) Heck, it’s even among the top results on Google for ‘qualitative salt analysis’. Yay me! CBSE Physics Practical data: Missing practical classes is a national sport in schools. This page has data from the demonstration experiments which students are supposed to have...

Jabberwocky v1.1g-nu

By on Jan 17, 2008 in On A Whim | 2 comments

In an update to the Jabberwocky v1.1 release comes an update for the graphics-mode version: Jabberwocky v1.1g-nu, which now no longer requires the user to separately extract the graphics libraries in his root folder. All that the user now needs to do is to keep the executable in the same folder under which the folder ‘Graphics’ is present. In short, just extract the file the way it is, get started!

Jabberwocky v1.1

By on Jan 16, 2008 in On A Whim | 0 comments

Jabberwocky v1.1 is out now and can be downloaded here. The fact the the user is no longer prompted to be shown the menu again (thanks to Rach for the suggestion). The program now asks for confirmation before editing / deleting any question from the database, reducing the chances that something may accidentally be done to the database. Path to the Borland Graphics folder has been changed. Password authentication / change now uses the traditional ‘Enter’ to terminate, rather than ‘Space’ in the earlier version. Using ‘0’ to exit a mode has been added to more functions. Thanks to all the people who wrote in with their suggestions / comments – me and Naman highly appreciate it. And thanks to Naman, my partner on the project, for bearing with me and my ‘Can’t compile the program at home’ shit. :) Planned for future versions: Adding the ability to keep scores for multiple teams in ‘Quizmaster Mode’. Some sort of password encryption? PS – Gaurav Trivedi, one of our Code Warriors, has created a pretty neat website creator as his project. Do check it out! Click here to download his cWeb3...

Jabberwocky v1

By on Jan 12, 2008 in On A Whim | 4 comments

At last, my computer science project is ready! Me and Naman present Jabberwocky – The Utterly Weird Quizzing Software. Bear with me, the ‘official site’ ain’t complete yet, I’ve pre-Boreds going on for Bob’s sake! If I get time, I’ll make a proper site, otherwise I’ll use a blog engine. Considering that in one we went through FOUR different versions on ONE day doing bug fixes, I’m sure a blog engine WOULD be a better idea. Which reminds me, I need to install WordPress on my hosting account, and get out of this shithole of Blogger soon. Click here to download Jabberwocky v1 (~200 KB). Read the ReadMe before starting off. The program comes bundled with 42 questions in its database, you can of course, add more. Suggestions are...

Class 12 Comp Sci Stuff : Postfix Conversion

By on Jan 5, 2008 in On A Whim | 4 comments

CBSE’s class XII computer science syllabus also happens to have infix to postfix conversions (and vice versa) as an application of a stack…without actually coding. Weird, or shall I say, good – because THAT sort of coding will knock the socks of most people. Anyway, I’ve given solutions to the conversion exercises given by our school. I hope they’re correct, and in case they aren’t, please do leave a comment to correct me. Postfix, also known as the Reverse Polish Notation, is something some friends of mine have a called a pain in the butt. Indeed, if you try to follow the algorithm given in the notes given in our school, you’ll find the procedure is not *that* clear. Although it’s based on Djikistra’s ‘shunting yard’ algorithm, you’ll find that this explanation is WAY better the one given in our notes. The Sumita Arora book’s description is OK too, so you may go in for that if you’re physically incapable of making a small mouse click (and perfectly capable of lifting a heavy book).
