To prepare for RRB JE CBT 2, aspirants should try to cover the technical part as it covers the
maximum weightage. The technical syllabus for various streams is provided in the further
sections of this blog post. Aspirants should note that they don’t need to go very deep in the
technical syllabus, unlike GATE or ESE. Since the RRB JE is a junior engineer level exam, aspirants should cover all the basics as well as theory and some formula-based numerical. Aspirants can also opt for the MADE EASY RRB JE course. The candidate should prepare a balanced study plan in which the non-technical part also gets enough time along with the technical syllabus. Subjects like physics and chemistry, basics of environment and pollution control, basic computer and applications, etc., are easy to score good marks in. Therefore, aspirants should try to score maximum marks in these subjects. Aspirants should also try to attempt a mock test to check their preparation level. Merely attempting a mock test just for the sake of marks is not enough; aspirants should also check their mistakes and note them in a register so that they won’t be repeated in the exam. Solving the previous year’s paper would be very helpful for the aspirants, as this would give them an idea about the level and type of questions that are being asked in RRB JE CBT 2. Along with regular studies, aspirants should take care of their health. Aspirants should stay consistent with their studies and keep their focus only on RRB JE CBT
