Hello,

You have not mentioned for which course you are looking for.  Even though all the exams have their own level of toughness, as the purpose of the entrance exams to get the best and out of many. All these exams can be cleared and one can score good marks, provided you work hard and give your best.

In the case of engineering entrance examinations,  exams such as EAMCET, UPSEE, KCET, VITEEE etc do not have negative markings. Obviously the competition for state level exams will be lesser than the national level exams. You can also try for entrance exams offered by some colleges for their admission like BITSAT for BITS, VITEEE for VIT, etc

So based upon the course the entrance exams will be different.

I suggest it would be better you start preparing for the toughest ones like JEE Advanced and Mains for Engineering, then the other exams will be much easier for you

Good Luck
