Hello dear student,
It doesn't matter where you have studied , the only thing that matters is how much subject knowledge do you have. Show SRM joint entrance examination is basically an entrance test for two and half hours which will be covering subjects that are physics, chemistry ,mathematics/ biology. The question paper will be MCQ type only and there will be no negative marking.
You can download the syllabus from the website of of SRMJEEE only . I hope this will be helpful for you dear student
Ofcourse you can. If you've made sure of the syllabus and studied hard then you can definitely crack SRMJEEE. SRMJEEE is an online exam so be prepared for it. Clear all the concepts and practice previous years question papers. And practice them all on computer as online tests are quite different from offline tests.
