Dear aspirant !!
Hope you are doing well !!
To join CIT (Central Institute of Technology) or any other engineering institute, the marks and eligibility criteria usually depend on the specific course you're interested in and the entrance exam requirements.
Since you've mentioned completing your 12th class 2 years ago and spending the past 2 years preparing for the NEET exam, here's what you should know:
For Engineering (CIT or similar institutes) : Most engineering institutes, including CIT, generally require JEE Main scores for admission to B.Tech programs. To be eligible for JEE, the typical requirements are:
Age Limit : The age limit for JEE Main is generally 25 years for general category candidates (with relaxation for reserved categories). Since you've completed your 12th two years ago, you should be within the age limit, but it's good to confirm with the specific institute for any age-related conditions.
NEET and Engineering : Since you prepared for NEET, it’s important to note that NEET is primarily for medical courses like MBBS, BDS, and related fields, so NEET scores are not relevant for engineering programs like B.Tech. However, if you are interested in medical engineering (like Biomedical Engineering), then NEET may have a partial relevance depending on the course and university.
Next Steps : You would likely need to appear for JEE Main if you haven't done so yet and meet the eligibility criteria for CIT or other engineering institutes.
It's also advisable to visit the official CIT website for the exact admission process and eligibility details. Let me know if you need further clarification or help!
Hello!!
The B.E./B.Tech program offered by CIT consists of 8 semesters (4 years) in duration.
A Pass in the HSC(Academic: both +1 and +2)or its equivalent with a minimum average percentage :
General Category 45 %
BC and BCM 40 %
MBC & DNC 40 %
SC/SCA/ST 40 %
A pass in any one of the HSC(Vocational Subject: both +1 and +2)as given below with any one of the Engineering related subjects namely Mathematics, Physics or Chemistry with minimum percentage as given below
General Category 45 %
BC and BCM 40 %
MBC & DNC 40 %
SC/SCA/ST 40 %
Dear
To join CII (Central Institute of Technology) or any other institute, the eligibility criteria generally depend on the entrance exams, such as JEE (Joint Entrance Examination) or other specific exams for the college you are interested in.
For CII or similar institutes, you would need to:
Eligibility for JEE : Since you completed your 12th two years ago and have spent time preparing for NEET, if you are looking to join an engineering program, you would likely need to appear for the JEE Main and Advanced exams. Usually, for JEE eligibility, the candidates must have passed the 12th board exam with Physics, Chemistry, and Mathematics as core subjects.
Age Limit : There are generally age restrictions for JEE, and candidates must be within a certain age limit (usually 25 years for general candidates, with a relaxation for reserved categories).
Marks Requirement : For JEE Main, you typically need a minimum of 75% marks in your 12th board exam (or be in the top 20 percentile in your respective board exam) to be eligible for admission to NITs and other centrally funded institutions. The exact eligibility for specific colleges like CII will depend on their own guidelines.
Valid NEET Scores : Since you spent two years preparing for NEET, if you are still interested in pursuing a medical field, NEET scores can be considered for admission to medical colleges, but for engineering or technology courses, NEET scores generally won’t be relevant unless you are looking for a course in Biomedical Engineering or a similar niche
Dear
The exact number of NEET aspirants in India who do not give the NEET exam due to age-related issues is not officially documented. However, this situation arises because the upper age limit for NEET has been a significant point of concern for many students. As per the official guidelines:
Age Limit for NEET : The eligibility criteria for NEET state that candidates must be at least 17 years old by December 31 of the year of admission, and the upper age limit is 25 years (with a 5-year relaxation for SC/ST/OBC candidates).
Impact of Age Limit : Many aspiring medical students, who may not fulfill the age requirement or who take time to prepare for the exam after completing their 12th grade, are often unable to appear for NEET. This has led to frustration among many students who wish to pursue a medical career but cannot due to age restrictions.
However, the number of students affected by this issue varies every year, and it would require data from the National Testing Agency (NTA) or specific surveys to determine a precise figure. If you’re concerned about age limits or looking for alternative routes to medical education, there are a few options, like exploring medical colleges abroad or looking into alternative fields within healthcare.
If you want to stay updated on any changes in NEET eligibility or age limits, keep an eye on official announcements from the NTA or relevant education authorities.
Hi Nahid, There's no upper age limit for NEET, no aspirants are ineligible due to age and forced to take a drop year. The only age requirement is a minimum of 17 years as of December 31st of the year of admission.
