Almost all subjects are important because learning those topics will create a sense of aptitude and logical reasoning and thinking capabilities in your mind.

Still as far as mechanical engineering is concerned, physics and maths play the most important role.
But also some basics of chemistry should be known.

You should focus right now on your 11th and 12th syllabus, better you will be prepared better will be your chance to get admission in a good college and branch of your choice.

 

Focus on your syllabus:-

 

Physics Syllabus:-

The physics syllabus will consist of Alternating Current, Oscillations, Heat & Thermodynamics, Current & Electricity, Units of Measurement, Electromagnetic Induction, Motion in one, two & three dimensions, Kinetic Energy, thermal and chemical effects of currents, Ray Optics, Capacitance, Heat, and Thermodynamic, X-Ray, Wave Optics, Radioactivity, Simple Harmonic Motion, Gravitation, Principals of Communication, EM Waves, Elastic Kinetic Theory of Gases and Vector Motions.

 

 

Chemistry Syllabus:-

The chemistry section will comprise of the chapters that include Transition of Metals, Bio-Molecules, Nuclear Chemistry, Electrochemistry, Polymers, Chemistry of Carbon Compounds, Organic Chemistry, Chemical Kinetics and chemistry in action, P Block Elements, Solid State, Coordination Compounds, Redox Reaction, Chemical Bonding, Alkanes, Alkenes and Alkynes, Chemical Equilibrium, Chemistry Thermodynamics, Aldehyde Ketone, Gaseous State, S-Block Element, Surface Chemistry, Periodic Classification of Elements, Solutions, Atomic Structure, Mole Concept & Electrochemistry.

 

 

Mathematics Syllabus:-

The mathematics section will be asked from Probability, Matrices & Determinants, Logarithmic Series, Differential Equation, Three Dimensional Geometry, Co-relation & Regression, Circles, Trigonometry, Co-ordinate Geometry, Vectors, and Calculus.

 

 

 

All the very best and good luck.
