Exam

No, appearing student can not apply for UPSC ALC exam. One need to have specific education requirements like LL.B. M. B.A. MSW PG Diploma in labor law etc.

As per my information, a 23-year-old person cannot join NDA as the age group required for NDA Entrance is between 18-21. So, I think you are ineligible for this.

Some universities that do not count GRE Scores are mentioned Below:
University of Cambridge
National University of Singapore
University of British Columbia
Monash University Australia.

You require at least a score of 65 in PTE to qualify for an Australian Permanent Residency or PR. However, the minimum level is competent English if you apply for subclass 189 or 190.

With a 5.5 score, you can apply for European countries such as Poland, Greece, etc. Where you can get an IELTS waiver, and the UK. Further, countries like New Zealand, Canada, Singapore, and Dubai includes colleges that accept 5.5 IELTS band score.

Overall band 5 is a low score and cannot be counted as decent. Instead of applying, I would suggest, re-take the test after 2 months. Study meticulously and know your basics first. First 1.5 month should be extensively dedicated to English Grammar and reading. In the rest 15 days, take mocks and time your tests. Evaluate your tests and improvise your weak areas. IELTS is not as difficult provided you study enough and know the flow of the exam well.

The West Bengal Residential/Domicile prerequisite is likewise appropriate for any seat under Tuition Fee Waiver (TFW) scheme. Every state have some quota for other state students. So you will not face any problem in admission through WBJEE in B.Tech courses if applied through other state quota.

Please make your question more clear, so that I can answer your question.

The minimum MAT cutoff score requirement of Christ University is 500 and above in Sep/Dec2022/Feb:2023. So MAT score above 600 can be the good for admission here. However confirmation is required from CU regarding acceptability of May MAT score.
