Set weekly targets and aim to achieve the same before time. Why I am focusing on a weekly timeline is because it gives you the flexibility to cover the targets while also accommodating other engagements!

So, at the start of every week segregate topics which you will be studying that week and build a daily plan like the one below:

30 minutes a day of reading + VA practice

1 Quant concept a day (theory)

1 LR set (from dedicated IPMAT Preparation Courseware)

15 minutes a day of quants practice

This can be changed according to when you are starting i.e. the time left for preparation. This particular target plan will work if you have around a year to prepare!
