What My Students Have to Say

You have made Chemistry so simple for my daughter. She says you are even better than her professor and that her classmates would like to have you as her professor.
Meera, California

I have gained immense confidence after studying with the tutors on this website. I recommend the tutors here to everyone who needs online tutoring and homework help.
Sarah Hamilton

My exams had gone off so well after my sessions for MCAT exams with you. I have thoroughly understood Aromatic Reactions, Alkenes and Alkynes after studying with you. Thank you so much. You are the best Chemistry Tutor I have ever had.

Subject:

SAT Math Exam

Date of Exam.

The SAT subject tests are offered in Oct, Nov, Dec, Jan, May and June every year. For 2011, the test dates are May 7, 2011, Jun 4, 2011 .

The Exam

Levels. The SAT Math exam is conducted for two levels, Level I and Level II.

Format of the Test:-The test comprises 50 multiple choice questions.The tests cover content typically taught in the first three years [For Level 1] or four years [For Level 2] of college-preparatory mathematics

Use of Calculators:-

Both tests are developed with the expectation that most students are using graphing calculators. Calculators are premitted in both the exams. For 40-50% of the questions on Level 1 and 55-65% of the questions on Level 2, a calculator may be useful or necessary.
No substitute calculators or batteries will be available at the test centre. Students may not share calculators.

However the following are not permitted:

Power Books and Portable Computers
Electronic Writing Pads or Pen-Input/Stylus-Driven Devices (e.g., Palm, PDAs, Casio ClassPad300)
Models With QWERTY [i.e. Typewriter] and Keypads [e.g. Ti-92, Voyage 200]

Study Packages

The study packages for SAT Math Exam have been designed to cover the complete SAT syllabus for Math. The package can be customized as per your requirements.

Diagnostic Test. The students are first put through a diagnostic test to assess their strengths and areas where they may need greater emphsis.

Study Material.I use the relevant study material for SAT Math Exam for comprehension of the subject in detail. I use my own presentations which have been prepared keeping the requirements of the students in mind.

Study Topics.Thestudy topicswhich are covered in the SAT Math exam for level 1 and level 2 have been given out below.
