Hello,

Yes, it is enough to study for four to five hours but you have to focus. The hours doesn't matter as long as you have full concentration on the studies. Keep away all the distraction like social media accounts should be closed for a while, cell phone off among other things. I totally support time table , time managment but only if u can execute your plans according ur plans and not regret at night bout thinking you coudnt do as planned. And maintain your consistency that is so important and no procrastination is to be done keep it in mind….. After the syllabus is covered or even when 70% - 80% syllabus is finished you can start giving full length tests and analyze your mistakes and rectify them and don't repeat them in next tests and at the last you will be at the next level of your preperation where you will feel so confident from inside and if you will follow these things you will get a good rank.

Hope this helps!!
