Diploma

Bachelor of Technology is the best course to pursue after completing Diploma. It is generally recommended to Diploma holders to apply for the B.Tech course, which I will also recommend to you. There will be no need to pursue the 4 years of B.Tech. Since you are Diploma holder you can apply for the B.Tech through lateral entry scheme. Under the lateral entry scheme, Diploma holders can take admission directly in the second year of Bachelor of Technology. There is no need to do first year. You can take advantage and apply for admission through lateral entry. Before you go ahead let me point out drawback of going with lateral entry scheme. The best engineering colleges in the country like Indian Institutes of Technology and National Institutes of Technology do not offer lateral entry admission. If you are keen on completing B.Tech from these colleges then you will have to appear for the Joint Entrance Exam. However if you don't really have any urge to take admission in IITs or NITs then go ahead with lateral entry admission. You will have to appear for Lateral Entry Engineering Test. You must have 60 percent marks in Diploma to appear for the exam. After clearing the LEET you can take admission in the seats reserved by the Engineering colleges for the lateral entry admission. There are other entrance exams apart from the LEET. Some of these exams even accept candidate with 50 percent marks.
