hi,

see in official website of sant longowal institute of engineering and management has no previous years sample paper for lateral entry entrance test. so candidates have to prepare by self study.. generally if you have go through many state wise lateral entry test papers like JILET, bihar lateral entry exam questions are based on three years diploma course. since your stream is electrical you have to revise the full 3 years diploma syllabus. generally mcq questions are asked in many exams. I have mentioned some of the books name below which would be helpful for exams preparations.
