Dear aspirant

There is no guarantee as such that if you practice mock test of biology full syllabus every two day's, that you will be able to score full marks in biology.

Biology is subject where you need to be consistent without any lag then only you will be able to score maximum,it's not like you are not reading ncert books and you start preparing for last 3-4 months seriously and you are trying to achieve maximum marks then it's least likely to be possible.

First of all as you are first dropper so i would suggest that you should point your weak chapter in biology both class 11th and 12th then clear your every concept from those chapters as soon as possible and attempt questions from those individuals chapters and see how you from. If you find improvement proceed like that.

Full syallabus test are mainly recommended in last 2-3 months before exam on daily basis when you have completed whole syallabus 2-3 times and that time you will be confident also. That time you should check the chapters which you are making more mistake,give them a reading immediately after that.

If you start attempting full syallabus test from now only without giving proper reading then sometimes you may score very badly and you might not see improving your marks,which can ultimately lead you to get depressed,so take care of that and don't do in such manner.

Never stop studying ncert books of biology, on daily basis you should try to complete one chapter so that by the exam time you can finish your 3-4 reading of full syallabus of biology. And every time you finish reading chapter, practice previous year question of neet from that particular chapter.

This way will be more helpful for you to score maximum marks in biology.

Although everyone have their own way to learn,so which ever suits you,keep going with that just make sure you are improving on daily basis.

Hope this helps you in someway

Best wishes!!
