    Hello,

    GATE 2026 score of 320 (OBC, AIR 1633 in XE), admission to top IITs will be difficult. However, you may get opportunities in newer IITs or lower-demand branches in later or spot rounds. You have better chances in NITs, IIITs, and state universities through CCMT counseling. PSU opportunities are

    Every PSU has different cut-off marks and eligibility. Hence, it is suggested to apply for PSU after checking the eligibility. Also, they do not reveal the marks of the finally selected candidates. So, wait for the final merit list.

    Yes. You can. GATE eligibility specifies that students in their 3rd year and above can appear for the exam. Since the results are valid for 3 years, you can use the same for your admissions.
