Before starting with the strategy I would like to answer a common question: What is the final score vis-à-vis correct attempt? It is true that there is heavy moderation of marks in science subjects especially in mathematics. But despite that it is possible to score very high. I got 390/600 in CSE-2008 and 427/600 in CSE-2009. My final score and correct attempt paper wise is:
2008: Paper I: I got 184/300. Correct attempt was 261/300. Paper II: I got 206/300. Correct attempt was around 250/300.
2009: Paper I: I got 209/300. Correct attempt was 300/300. Paper II: I got 218/300. Correct attempt was 285/300.
In the correct attempt I have counted only those answers which are absolutely correct. Paper I is relatively easy so the reduction is huge. Also do not confuse the term scaling down as only multiplication by a constant factor (some says scaling is 0.6 or 0.7). The statistical formulas are more complex and the subtraction part has larger weightage I guess (seeing the mark trends of all the students in last 2 years).
General tips for preparation:
1. While preparing one should not be bothered about the moderation/scaling. Target should be to score maximum possible marks.
2. In Paper I try to cover all the topics. If time does not permit then cover dynamics and statics from 12 markers point of view.
3. In Paper II focus on the topics: Complex Analysis, Linear Programming, Partial Differential Equations and Numerical Analysis. Rest of the topics should be covered from 12 markers point of view.
4. Make a fair copy and practice all the previous year questions in it.
5. Practice with pen and paper(Many aspirants take this point casually and just read the solved examples)
6. Do at least 3-4 papers in exam like conditions.
General tips while attempting the paper:
1. Ordering of questions does not matter. Attempt the questions which you know the best at the start.
2. Try to finish each question in the 75-80% of the allotted time. For example, a 15 marks question has allotted time of 9 minutes. Try to finish it in 7 minutes. Rest 2 minutes must be spent on revising the answer. Rechecking entire paper at the end may not be possible. Try to work out the answer quickly in rough space. All this is important because wrong answer may carry heavy penalty.
3. All the trivial calculations (like simple integration, algebraic and trigonometric manipulations) can be done in rough space to save time (I believe that showing them in answer might not carry any weightage).
I will also upload some of the answers which I wrote in the paper. In the next articles I will be sharing the detailed strategy for both the papers.
