The CSV file is like below,
ID,coaching_centre,LOCATION,STD_NAME01, STD_NAME02
1,'Oracle Coaching','Dhaka','Momin', 'Abdul'
2,'ISP Coaching','Jhenidah',
From the CSV file first 3 fields will be loaded as usual. But the last fields that is STD_NAME01, STD_NAME02 is bit complex. For each std_name every first three entry from the CSV file will be there. For example for std_name Momin both
1,'Oracle Coaching','Dhaka' and
2,'ISP Coaching','Jhenidah'
rows will be entryed.
Similarly for std_name 'Abdul'
all first three rows will be entryed.
In the table there is 4 columns.
ID,coaching_centre,LOCATION and STD_NAME.

The CSV file is like below,
ID,coaching_centre, LOCATION, STD_NAME01, STD_NAME02
---------------------------------------------------------
1,'Oracle Coaching', 'Dhaka', 'Momin', 'Abdul'
2,'ISP Coaching', 'Jhenidah',
From the CSV file first 3 fields(ID,coaching_centre, LOCATION) will be loaded as usual.
But the last two fields that is STD_NAME01, STD_NAME02 is bit complex. For each std_name01 and std_name02 every first three fields from the CSV file will be loaded.
For example for std_name01 'Momin' first three fields (ID,coaching_centre, LOCATION) contained values
1,'Oracle Coaching','Dhaka' and
2,'ISP Coaching','Jhenidah'
will be loaded into oracle table.
Similarly for std_name02 'Abdul'
first three fields will be loaded.
In the table there is 4 columns.
ID,coaching_centre,LOCATION and STD_NAME.
Whenever any entry of std_name01 ('MOMIN') (i.e from CSV file field) will be loaded the std_name values will be 'Momin'.
For every STD_NAME02 std_name value will be 'Abdul'.
A bit detail my final table will be,
ID,coaching_centre, LOCATION, STD_NAME
---------------------------------------------------------
1,'Oracle Coaching', 'Dhaka', 'Momin',
1,'Oracle Coaching', 'Dhaka', 'Abdul'
2,'ISP Coaching', 'Jhenidah', 'Momin'
2,'ISP Coaching', 'Jhenidah', 'Abdil'
In CSV file std_name01 and std_name02 entryed are now in rows under std_name.

You can use "concatenate 3" to consider every 3 rows as one logical record. Then you can do three loads using the std_name1 and std_name2 from the first line for each of the three rows. Your delimiters will need to be consistent. In the following, the test data has a comma at the end of each line.
-- test.ctl:
load data
infile *
concatenate 3
into table test_tab
trailing nullcols
(id terminated by ',',
coaching_centre terminated by ',',
location terminated by ',',
std_name01 terminated by ',',
std_name02 terminated by ',')
into table test_tab
trailing nullcols
(filler1 FILLER position(1) terminated by ',',
filler2 FILLER terminated by ',',
filler3 FILLER terminated by ',',
std_name01 terminated by ',',
std_name02 terminated by ',',
id terminated by ',',
coaching_centre terminated by ',',
location terminated by ',')
into table test_tab
trailing nullcols
(filler1 FILLER position(1) terminated by ',',
filler2 FILLER terminated by ',',
filler3 FILLER terminated by ',',
std_name01 terminated by ',',
std_name02 terminated by ',',
filler4 FILLER terminated by ',',
filler5 FILLER terminated by ',',
filler6 FILLER terminated by ',',
id terminated by ',',
coaching_centre terminated by ',',
location terminated by ',')
begindata:

Just a bit clarification is it possible to create table as,
SCOTT@orcl_11g> create table test_tab
2 (id number,
3 coaching_centre varchar2(20),
4 location varchar2(15),
5 std_name01 varchar2(15))
6 /
And data of std_name02 from CSV file will be loaded to field std_name01.

Your descriptions and your data examples don't seem to match. I suggest that you use SQL*Loader to load the data into a staging table as is, then use SQL commands to insert the data from the staging table to the target table in the manner you want.
