First of all if you want to pursue engineering, I would recommend you to focus more on engineering entrance exams rather than your 12th percentage as every competitive exams requires a minimum of 75% marks as an eligibility criteria so even if you score in the range of 75-80% marks that would suffice .
Start preparing for exams like JEE, BITSAT, VITEEE and any other state entrance exams according to your location and opt for the engineering branch that you love the most and are most passionate about and analyze the future work conditions, scope and growth prospects before taking admission.
You can also opt for psychometric test comprising of aptitude, personality and career interest to clear your confusion.
