Scoring 40 marks in the GATE 2022 exam for Civil Engineering may not guarantee admission to top NITs for M.Tech, as the competition and cutoffs are high. Typically, candidates with a higher score, especially above 55-60 marks, have a better chance at securing a seat in NITs for Civil Engineering. However, the actual cutoff depends on factors like the number of applicants and seat availability, so it's important to keep an eye on specific NIT cutoff trends for more accurate predictions.
