Dear Sir,

These are all the tips I managed to note down during class today.
Give the Physics exam first during the SAT II exam and then Maths.

In the case of Physics, after the first 10 minutes, 25 questions should be done. It is because the questions are arranged in the ascending order of difficulty and therefore, you have easiest questions at the start. The next 20 questions should take up around 20 min and the final 30 questions will take up 30 minutes of your time.

Don’t leave out more than question for Physics. For Maths, don’t leave even one question unanswered.

PHYSICS
Some information
  • Rate of fluid = velocity of fluid × Cross sectional Area
  • Total magnification = product (multiply) of the magnifying power of all the lenses
  • Human retina is a convex lens
  • When an object is placed at the focal point of a lens, no image is formed.
  • When an object is placed at 2F (twice the focal length), the image and object sizes are equal.
  • Silver is the best conductor, but it is very expensive to use. The next best conductors are aluminium, copper, and nichrome
  • Dime (1 cent); Nickel (5 cents); Quarter (25 cents).

Problem Areas
  • Gravitational Potential and Electric Potential
  • Energy related to satellite
  • Sparknotes Test 2 Question : An object of weight 200N is at rest. Its coefficient of static friction 0.8 and its coefficient of kinetic friction is 0.2. how much force is needed to move the object and maintain its motion at constant velocity?
  • A string is vibrating. If tension is doubled, what happens to its velocity?
  • To what significant figure should the answer be written?
  • Special Theory of Relativity

MATHS IIC
  • Trigonometry formulas
  • Functions
  • Trigonometry and Functions should be done from Sparknotes
  • Determinant of matrix
  • Distance between a plane and a line
  • Ellipse 
  • Graphs of eand ln x


Check some problems in Sparknotes Test 2
Read Barrons Chapter 5 (Miscellaneous)
Major Formulas should be accessed from Barrons

NOTE:


  • The tests from Sparknotes will be of help for the real SAT II exam. Barrons will only increase your knowledge on that particular subject but might NOT be of any REAL assistance during the real SAT II exam in most cases.
  • With relation to no 67 of Test 3 of Sparknotes Physics - REMEMBER the following - 
    • Charge remains the same.
    • Voltage decreases.
    • Capacitance increases.
    • Electric Field decreases.
    • Energy decreases [1/2 CV square]
  • Adiabatic Expansion of Gas [Check the Garry Graff PDF version].
  • V= Root Over (TL/m) [Ref to Sparknotes Test 3 Q No 70]
