Preparation advice
hey guys! I am a final year student and preparing for gate 19. Preparation is going well but the problem I am facing is with time left. Since 2 months are left for the exams and semester exams are also round the corner, so I am thinking of skipping over ... and previous years questions. Though I will be taking full Mock tests for sure. Is it a wise choice. Need some advice. :)
