See its good that u had planned and u want to get rank ..........i want to suggest that :
1. When u complete 1 subject and after that u dont read it for 3 Months u have to start from beginning.If u start in May FM and then read it directly september ur hardwork will be waste.
2.When u read 1 or 2 subject of all month u will be bored and u wont be able to give 100% quality.
3. For rembering revision is must and it must be at very short time. For example YOU HAVE TO GIVE DAILY 1 HOUR FOR REVISION. You should plan your schedule accordingly so that you revise it atleat in a week.
If in a theory subject when u read any chapter you have to give e.g., 7 hours. Than after 2 days just shuffle up your pages in your boring time. It will take 2 hours. After a week revise it and it will take30 minutes.Than after you will have to just see overview and remeber after that atleast in a week atleat one time you have to read it in a fast track way and will take hardly 10-12 minutes(This you have to do when you are feeling bored not in a regular time)
CRUX : Continious revision is must
4. I advise you to divide a subject in 16 parts : That is 4 Months* 4 Week.
So divide your 8 Subjects into 8*16=128 different parts.
Now make sequence starting from most difficult parts.Remeber you will do continious revision.When u read today 2 parts than as i had mentioned above you will daily do revision as i mentioned above.
5.At september you will be through and no part would be old or untouched for long time.
After september start write 1 past paper and 1 past RTP daily as at that time you will give atleast 8 -10 hours for ur studies and do revision in rest time. Learn from your mistakes u had done in writing practice paper daily.
If you follow this you will be 100% confidence at exam day and even you will not feel bored as you are changing the subject while reading.
Rest is your choice plan and read in a manner in which you are comfortable.
But whatever you plan be strict to it and follow it.
ALL THE BEST TO YOU............
