my total percentage in class 12th pcmb with English and ip is 55% in which I have got rt in chemistry (additional subject) so will I be able to get admission in btech ?? and if not then what courses will be good for me

Scoring 55 in PCMB with English and IP is a bit low for most B. Tech admissions, as many colleges require around 60 or more. Since you got RT (Re-appear) in Chemistry, clearing that exam is important to improve your overall score. If BTech seems tough right now, you can explore other good courses like BSc in Computer Science, Information Technology, or Mathematics. You could also consider diploma courses in engineering or related fields. These can open doors to jobs or further studies later. Focus on improving your marks and choose a course that matches your interests and strengths.
