Medicine Entrance Exam

Three questions can be challenged to get bonus
marks for those questions according to NEET 2019 answer key.
1. Chemistry: The colloid question must be given as a bonus as it had two options to be correct. So, many might have left that question fearing they will be awarded negative marks.
2. Physics: Magnetic field inside the cylindrical conductor
question. They didn't mention whether it is a hollow or solid cylinder. So, I considered it as hollow one (by default) and considered magnetic field inside the hollow cylinder to be zero and marked that option. But NTA has considered it to be a solid cylinder. Whose mistake is this? Why should students get affected? It's better they give bonus marks to that question instead. As even a single mark is important in determining the rank of the candidate.
3. Physics: Voltmeter and ammeter question. If you don't
consider it as ideal. We will get a different answer.
I request students who got confused in these questions to
challenge these questions to get bonus marks as even a single mark can be a deciding factor.
Thanks.

Doubt. The most positive thing I have ever come across about it is if you are actually reading, occurring doubt is natural. One who has no doubt at all, maybe he is not clear about the concepts until now. So, first, be happy if you have doubt. Now Clearing the doubt within time is important or else it may hamper NEET result.
To clear a doubt, you must understand that topic from the very start. Take guidance from your seniors. Stick to your concepts from NCERT or you may contact your school faculty as well. Cross check if your doubt is genuine or it might be from exceptions. Be clear about the concepts. The more you will revise the more chances are there for the things to be cleared.
