There are many students who think that Chemistry is not related to Physics and Mathematics and should be removed from engineering entrance and such people do not prepare chemistry spend all their time in Maths and Physics and at the end lose their precious rank because of chemistry.Many topics in Physical Chemistry are problem oriented and are similar to Maths and Physics...But some times they may require you to remember some concept or some equation....

So this is how you must quantify your Engineering Entrance examination

1. Maths - To Test your speed
2. Physics - To test your Analytical thinking
3. Chemistry - To test your Memory
4. English - To test your Communication skills
5. Logical Reasoning - To test your reasoning skills based on logical thinking

Few things to keep in mind while preparing for Bitsat Chemistry...If you follow them you will surely get a good score in Bitsat

1. Prepare only from the syllabus given in the brochure.(Click here for the Bitsat syllabus)
2. Most of the time students try to read the same topic from different books and wont be able to complete the syllabus.Prepare from one of the good books like Arrihant etc for problems but for theory preparing from NCERT books will help you score more.In short study from your NCERT text books.
3. Remember that chemistry is the part in any competitive exam where you spend the least time and can score maximum marks if you prepare properly.
4. Spend atleast 1 hour everyday from now on to study new topics in Chemistry(I have given a list of new topics below).
5. Bitsat Chemistry has lots of memory based questions and it is a must to by heart them.The good thing about memory based questions is that you dont spend a lot of time in solving them.
6. Here are few new and important topics in Bitsat Chemistry which are different from your normal preparation for other exams and can expect direct memory based questions

* Petroleum: Composition and refining, uses of petrochemicals.
* Carbohydrates: Classification; Monosaccharides; Structures of pentoses and hexoses; Anomeric carbon; Mutarotation; Simple chemical reactions of glucose, Disaccharides: reducing and non-reducing sugars – sucrose, maltose and lactose; Polysaccharides: elementary idea of structures of starch and cellulose.
* Proteins: Amino acids; Peptide bond; Polypeptides; Primary structure of proteins; Simple idea of secondary , tertiary and quarternary structures of proteins; Denaturation of proteins and enzymes.
* Nucleic Acids: Types of nucleic acids; Primary building blocks of nucleic acids (chemical composition of DNA & RNA); Primary structure of DNA and its double helix; Replication; Transcription and protein synthesis; Genetic code.
* Lipids, Hormones, Vitamins: Classification, structure, functions in biosystems.
* Polymers: Classification of polymers; General methods of polymerization; Molecular mass of polymers; Biopolymers and biodegradable polymers; Free radical, cationic and anionic addition polymerizations; Copolymerization: Natural rubber; Vulcanization of rubber; Synthetic rubbers. Condensation polymers.
* Pollution: Environmental pollutants; soil, water and air pollution; Chemical reactions in atmosphere; Smog; Major atmospheric pollutants; Acid rain; Ozone and its reactions; Depletion of ozone layer and its effects; Industrial air pollution; Green house effect and global warming; Green Chemistry.
* Chemicals in medicine, health-care and food: Analgesics, Tranquilizers, antiseptics, disinfectants, anti-microbials, anti-fertility drugs, antihistamines, antibiotics, antacids; Cosmetics: Creams, perfumes, talcum powder, deodorants; Preservatives, artificial sweetening agents, antioxidants, and edible colours.
* Other Industrial Chemicals: Dyes: Classification with examples – Indigo, methyl orange, aniline yellow, alizarin, malachite green; Advanced materials: Carbon fibers, ceramics, micro alloys; Detergents; Insect repellents, pheromones, sex attractants; Rocket Propellants.

Also you must be good with your experimental chemistry i.e. the your Chemistry laboratory experiements.

Remember the more the time you spend in preparing for Chemistry the better your final score.Chemistry is the place where you can save time in the exam which can be used effectively in Maths and Physics.
