Guys pls let me know what is wrong wid below prediction?
12th June CRS: 463
*Apart from below 3 assumptions rest of calculation is based on facts and figures
Assumptions made:
1. Same no of 450+ inflow will continue in June ie 223 per day
2. Draw comes on 12th June with 3350 ITA
3. Out of all candidates in range of 450-470:
a. 60% are from 450-460 slab
b. 40% are from 461-470 slab
Prediction starts:
After 1st May:
470+ = 0
450+ = almost 0
On 24th May, 450+ = 5353
450+ increase per day= 5353/24 = 223
So on 29th May, 450+ = 223*28= 6244
On 29th May draw 470+ candidates removed= 3350
Remaining (450-470) after 29th May = 6244-3350= 2894
From 1st May to 29th May:
470+ added= 3350/28= 120 per day
450-470 added= 223-120= 103 per day
450+ candidates added by June 12th:
470+ = 120*14 = 1680
(450-470)= 103*14= 1442
Total 450+ on 12th June = 1442+1680+2894= 6016
*2894 are leftover from previous draw
*1680 are 470+
ITA to be issued on 12th June= 3350
If we remove 470+ from 3350, then,
ITA issues to (450-470) scorers = 3350-1680= 1670
*This 1670 number will help reducing the cut-off
Now we need to calculate, how many candidates are sitting on a particular score, which is quite tough, let me give a try:
(450-470) candidates in 12th June draw= 6016-1680= 4336
Now I divide 4336 in two slabs, assuming density is higher in 450-460 range
Slab 1: (450-460) = 60% of 4336= 2601
Slab2 : (461-470) = 40% of 4336= 1735
No. Of candidates on each single score from 461-470= 1735/10= 173.5
Decrease in CRS score = 1670/173.5= 9.62
Hence my prediction = 470-9.62= 461 appox.
Now I put in some negativity factors which I cud not foresee and score can be 461+ 2= 463
In the same way you can calculate 26th June draw
