APTI APTI APTI!!!

Hello I am a third year student in a third tier college, I am pretty good at coding skills, let's say a Lil above average in problem solving questions. My only worry is aptitude rounds, I am weak at apti as well as MCQ type questions,I watched several YouTube video for guidance but none of them are clear, I started solving R.S Aggarwal a month back but still I am underconfident when it comes to apti. I would really appreciate some suggestions.
