Weakness & Remedies

 

The following were observed as the candidates’ weaknesses.

  • Poor problem-solving skills especially when it is numerical;
  • Inability to interpret and plot graph correctly;
  • Poor choice of scales for graph;
  • Inadequate knowledge about thermionic emission, elasticity (young modulus), dimension analysis, pn-junction (V-I characteristics, forward and reverse biasing), pressure in fluids, impulse as related to change in momentum.
  • Inability to correctly draw the magnetic field pattern around a bar magnet;
  • Incorrect definition of neutral points, load and velocity ratio.

The following are the suggested remedies:

  • Regular practice on problem solving;
  • Attention to correctness of definition;
  • Learn to plot graphs correctly;
  • Pay attention to topics like the thermionic emission, waves, heat transfer, radioactivity and elasticity.
