Maths Spl

The important points to be followed for preparation of mathematical sciences are:
For part A, practice some good books of General Aptitude.
For part B, a practice of your subject is must since you have MSQ (multiple select questions) in which multiple options can be correct.
For part C, again, the subject knowledge is a must. This part also contains MSQ type of questions.
For detailed preparation tips, here are some points:
Make a plan about the studies and follow some good books. Prepare short notes and handbook for formulae & concepts which can be helpful at the time of revision. Be selective with the questions in the exam as there is negative marking in both part A & B. Try to give mocks which will be very useful for your introspection and give you an idea about how to attempt the questions in the exam.
Hope this helps!

To know if education is really the right career path for you, make sure you have an understanding of what makes a good teacher and that you have the skills and characteristics compatible with teaching. To be a good teacher, you must enjoy being around other people and interacting with them, especially young people. Teaching is a social job that involves constant interaction with others. Good teachers are also patient. If you lose your temper easily, a school setting may not be the right workplace for you. Teachers are flexible and good at quick decision-making. They should be able to make adjustments when things don't go exactly as planned (because they often don't). Teachers must be strict to an extent and able to enforce rules, but they also need to pick their battles. Most importantly, teachers care. They care about their students and the students' success. Without this characteristic, being a teacher will become a chore after a while. If you feel passionate about a particular content area or about learning in general and you truly care about others, you have the potential to become a great teacher.
