Diploma

Hello Mahesh,
Yes, getting entry through lateral entry is the best. But presently, unfortunately almost all states have restricted this to students from their state only. You will have to find from RV college about their specific requirements or eligibility if any.

Yes, you can get admission easily and if you had also done 12th class. You can take admissions in PG.

Hi,
Yes, you can get admission in Diploma engineering but I am afraid as its 14th of July and admission seats are reserving with a boom so you are advised to immediately contact Diploma colleges for admission process.

Hello Naveen,
Yes, you need to give JEE Mains and secure a good rank like 20000 and below to get good NITs. You need to prepare separately as the questions are from PCM based on class 11&12 syllabus (NCERT).
