JEE Main

Hi Lovey,
As marks reduce, ranks increase rapidly. Suggested either an exponential function or a polynomial one. Got sufficient data by asking students to send me their marks and ranks – experimenting with the data found a reasonable fit with a formula as rank = ((k – marks) / n)^p.
Thus for 2010, rank = ((480 – marks) / 55)^5.5;
for 2011, rank = ((520 – marks) / 55)^5.5;
and for your year, 2012, rank = ((430 – marks) / 45)^5.5 worked very well (obviously, there is disparity between actual and calculated – more at the top level ranks).

Hi Lovey,
Personally, I don't think they can be compared. Both have different aspects.
JEE BARCH
It includes engineering level maths. You'd prepare for it the same way you'd do for paper 1 maths.
The aptitude section is very easy. Gk and logic questions are easy to crack.
The drawing section isn't very demanding and is just a basic approach.
It is 3 hours paper. ( maths and aptitude. +Drawing paper)
NATA
It includes general maths. The one you studied in 9th-10th std. Hardly 2-3 questions are expected. (Included in the online test among the 40 questions)
It has a drawing paper which requires you to analyse views (like bird's eye view, ant's eye view etc) ,It is tougher than JEE drawing paper.
Next is an online test which consists of 40 questions related to architectural awareness, analytical problems, aesthetic sensitivity and visualization. The questions asked here are tougher than JEE aptitude section.
You get 3 hours. 50 mins for online test and rest for drawing test.
So JEE has tough maths. And NATA has tough online test. Drawing can be handled pretty well in both the exams, if you get the concept thoroughly.

Hi Sneha,
Jee mains and BITSAT are relatively of the same level though Jee Mains is getting tougher every year. Well for Jee mains, solve NCERT Textbook Exercises and NCERT Exemplar of PCM thoroughly.
What I have realised is that they ask very typical objective questions from chemistry and maths. In physics, I would recommend you to go through the papers since the physics section is relatively tougher. For Jee Mains, also do topics like statistics, mathematical reasoning since they are very easy and fetch you marks. Download Jee mains 2014 and 2013 online papers also, it will give you an insight of the variety of the questions they ask.
As for BITSAT, it has a little different pattern. What I found interesting is that I had bought a Bitsat prep CD which has a number of practice tests, and honestly this year there were a lot of number questions that I had already done from ones in the CD. BITSAT also has an English section and Logical Reasoning section which is relatively scoring. Chemistry in the paper is a little weird, some questions they asked are not in NCERT text.
Overall, revising, re-revising concepts and practicing will definitely help you score better. For detailed chapter wise analysis go to : MY SPYGLASS. The blog will definitely help you out.
