With 50 percentile in the MHT-CET exam, admission to Computer Science Engineering in top or mid-tier government and private colleges is unlikely, especially under the general category. CSE is one of the most competitive branches, and the cutoffs for it usually fall much higher, often above the 85th percentile even in less competitive colleges.
However, you still have options. Some private colleges in Maharashtra accept students with lower percentiles, particularly in the later CAP rounds or through institute-level quota. These colleges may have management seats or unfilled seats in emerging CSE-related branches like Artificial Intelligence, Data Science, or IT. Your chances will improve if you are open to considering these specializations and if you closely follow the counselling rounds.
