Hi Aspirant,
Time matters but concentration matters more.If you can pursue hard work and concentration level for the 18th months then you can surely succeed.Cracking JEE advanced lies in understanding the fundamentals along with practising lots of numericals and previous years paper to understand the pattern.So study hard and you will surely succeed.Practise lots of maths since the maximum number of marks you can score from that part.
Hope it helps!!
