Engineering Sciences PCSI (Engineering Prep) Revision Sheets
Engineering Sciences (SII) in PCSI share a common curriculum with MPSI for first year. They train systems thinking combining mechanics, automatic control and power electronics.
Engineering Sciences curriculum in PCSI (Engineering Prep)
The curriculum covers six competencies (analyze, model, solve, experiment, communicate, design). Concretely: solid kinematics and statics, power transmissions, linear servos (transfer functions, stability, performance), physical system modeling (mechanical, hydraulic, electrical), functional analysis (SysML, FAST, FMEA).

Tips to succeed in engineering sciences PCSI (Engineering Prep)
SII method is invariant: isolation → balance → projection → solving. Apply it systematically
For servos, memorize standard Bode plots (1st order, 2nd order, integrator, derivative)
Use labs as oral training: you'll be questioned on modeling choice justification
Work with Matlab/Simulink or Scilab to visualize time responses: more telling than symbolic calculations
FAQ — Engineering Sciences PCSI (Engineering Prep)
Is SII mandatory in PCSI?
Yes, SII is mandatory in PCSI for the entire first year (4 hours weekly). In second year, you keep SII if you choose PSI (Physics and Engineering Sciences), but drop it if you choose PC (Physics-Chemistry). The PC vs PSI choice happens in PCSI spring: PC for those preferring chemistry and pure physics, PSI for those liking mechanics and engineering.
How do I work servos in PCSI?
Three pillars: 1) Laplace — master usual transforms and their use to solve differential equations, 2) Standard transfer functions — memorize 5 archetypes (1st order, 2nd order damped/under-damped, integrator, derivative) and their Bode plots, 3) Performance — calculate static gain, speed (tau), precision and stability margin. 20-30 concours-style exercises per chapter is enough.
Do I need Matlab for PCSI SII?
Not mandatory but strongly useful. Scilab is free and perfectly suitable for visualizing step responses, Bode plots, Nyquist loci. Spend one hour weekly on Scilab for a month: you'll gain intuition on system dynamics — a benefit directly felt at concours, especially the system analysis paper.
