Tips to ace Basics of Computers and Computer Applications for RRB NTPC

  • The questions asked in the examination are static in nature, so, one needs to be thorough with the facts, figures, and data related to each of the topics.
  • The section doesn’t require an in-depth knowledge of Computer Science as a stream, but surely, requires a beginner to intermediate level of knowledge in each of the
    topics. So, one must prepare accordingly.
  • Shortcut keys related to various computer applications like MS Word, MS Excel, MS PowerPoint can be memorized by practicing them on a computer or laptop.
  • Number-based questions will be asked on the number system (converting one form of number system into another). Apart from that, no number-based questions related to Computer Science (for example, calculating the efficiency of an algorithm, computing the turnaround time of a given program/task, etc.) will be asked.
  • Short notes can be prepared for each of the topics mentioned above (from the internet or from physical books) and should be revised at regular intervals so as to keep them afresh in the memory.
