I took BITSAT today, May 17 2023. 9u201312 noon. I heard feedback from people saying it was difficult and tricky yesterday so I was expecting a paper with the difficulty of JEE Mains.I started with Maths(considering it to be lengthy) , it took me 45 min to complete it, wasn't really tough just basic stuff (weightage of probability, quadratic equations was pretty high). Although, I did spot one incorrect question asking the integral of 1/5(sin^x +cos^x).Then I started with Physics, it had some typical theoretical type questions, also some from the topics not in Advanced syllabus but the ones I could do were really easy, mostly formula based, I left about 5u20137 in Physics, then I went to chemistry (the weakest one for me) went through the inorganic, but organic was tough (at least for me), faced some non trivial questions from environmental chemistry and biology related topics (s block elements and hydrhad more weightage than I expected).Hereu2019s when things changed, I found out that to attempt the bonus questions we have to attempt all of the 150 first so I had to guess around 13u201314 (which I think reduced my marks a lot) the bonus ones were quite good ( the level was between mains and advanced), I could do about 9u201310 of the 12.Most of the questions from English and Logical Ability Section were of English, It included day to day language and grammar, few of the English word meanings were tough (3, I think)My final score was 370 (still can't believe I got 29 wrong).Tips:Revise Inorganic Portion and Electrochemistry (reactions at anode and cathode) thoroughly.Attempt the bonus section when you have 25 min remaining. Not more than that because the questions are not that lengthy.Try and play with the options, most of them give a clue to the answer, you can eliminate one or even two options in every question.List of Questions/Concepts used in the Paper:Chemistry: Hall Heroult Process, Dil. H2SO4 Electrolysis, Activation Energy, Rate Constant, NO2 and SO2 source, BH4- Hybridization, Hybridization Definition, Block for 112 Atomic Number ,Standard Configuration of F-Block Elements, Addition Polymers, Heat of Combustion, Hydrohalogenation, Thermal Stability of Group I Chlorides, Percentage of each element in an Organic CompoundEnglish: Arranging 6 Sentence so that they make a meaningful order, Word meanings (sagacious,catastrophe,hadnt even heard of the rest, sorry!) , Standard Grammar(prepositions,adjectives etc), Short comprehensions and inference from it.Maths: Divisibility questions (Eg: n(n-1)(2n-1) divisible by?, 2^(2n+1) + 3^(2n+1) divisible by?), Normal at Vertex to Parabola,Basic Problem on Eccentricity of Ellipse, Standard Deviation Implication, Scalar Triple Product where any two vectors are same, Locus of end arrow of sum vector where one is fixed and other is rotated, tan(inverse)(1-x)+tan(inverse)(1+x)=pi/2, Inverses of 3-4-5 right angled triangle, Collinearity of points in complex notation.Physics:Resistors are usually made of Carbon, Relative velocity of two identical projectiles thrown in opposite direction, Identifying the presence of hinge reaction force, power(work energy), Calculation of capacitance (series parallel only), Capacitance of octant of a sphere if capacitance of sphere is C, Radiation pressure on a surface with reflection constant r = I(1+r)/c, Photoelectric effect, Effect of change in attitude on period of pendulum, Pendulum in liquid of Density 1/7th of solid, Tension at the Highest point in Vertical Circular Motion, Kinematics Questions, Volume of Bubble is doubled when it reaches the top of the lake from bottom of the lake, calculate it's depth,Difficulty of Paper AnalysisSo there was a question, we were given force, area, and fractional change in length, it asked us to find energy stored which is basically the direct formula. You wonu2019t see a lot of these questions not more than 5u20136. You need to atleast apply what youu2019ve learned. If it asks us to find magnetic field at a point between two current carrying wires, you need to know the formula then know the direction and then you can calculate the magnitude (most of the paper is of this kind).Well, the usual stuff like when the question puts variables like a, b or c or alpha or theta into the given equations, rather than trying to prove the them the traditional way, take one of them or something easy to reduce your work and check options easily, also if in physics its about sphere inside sphere try considering inner sphere surface charge density to be zero instead of sigma...Its not a lengthy paper, you can complete it easily.u201dAlso when its something you do not expect, like what is celestial sphere? do not panic, read the options youu2019ll get the most appropriate answer. Remember, if you can eliminate 2 options out of the 4, Do not leave the question. One particular question was like the Advanced type, it said a circle was drawn to touch the coordinate axis, then it completed a full revolution by rolling on x axis. Find equation of circle after rotation. But the options gave away the answer in this case.Finally, if you guys have any specific question, then you can message me here.Lastly, relax and everything will fall into place hopefully. Good Luck :)
