Thank you sir for the great analysis. As I have said earlier, a novice will always be a novice until I become sound like you. I planned to remove the course unit as it is not needed for my project cos this is just for an upper elementary which require no course unit nor even faculty or department. I want to display data for a specified class to list the registered subjects such that if I click on a subject say English, it will take me to another form where I will be able to enter scores for each students in that selected class for the allotted subject 'English'. Please I will post the initial code for the tertiary in which I was trying to worked to change to the upper elementary.

Here is the real for Higher college which is name as studentlist.php

This code work by displaying the list of students in a selected class and if I clicked on a student, it will take me to the registered course/subjects for that student so I can be able to enter scores for the students. But what am trying to do is that, let assume we have 10 teachers, and each teacher take different subjects, such teacher will only be able to enter his own subject score. That is why I was trying to output the subjects instead of the students name and from the subjects, If I click say English, it should list all the students taking English instead of listing all the subjects for a specific students. A teacher teaches a class which comprises of like ten or more students, such will have to enter the score for his subject like English for all the students eg

Class Name: Year 11 Science [Subject: English]

SN | Students Name  |  Score

1.  |  Johnson Rufus  |   40 ----- the score will be computed by the teacher

2. |  Olumide David  |  30 ----- to be entered

3. |  Kayode Jon      |  40  ---- to be entered

Something like above.

 

But here is the code for the studentlist.php 

<?php

    include('../includes/dbconnection.php');
    include('../includes/session.php');
    error_reporting(0);

  ?>

In that case

When posting code, use the code button ( image.png.548bc5371c44e4e10560560512cd1be0.png)

When your teacher finds the student/course to add their marks, where are you putting those marks?

Okay sir, I will observe that when posting code next.

The marks will stored in the database result 

-- Table structure for table `tblresult`
--

CREATE TABLE `tblresult` (
  `Id` int(10) NOT NULL,
  `matricNo` varchar(50) NOT NULL,
  `levelId` varchar(10) NOT NULL,
  `semesterId` varchar(10) NOT NULL,
  `sessionId` varchar(10) NOT NULL,
  `Subjects` varchar(250) NOT NULL,
  `courseCode` varchar(50) NOT NULL,
  `courseUnit` varchar(50) NOT NULL,
  `score` varchar(50) NOT NULL,
  `scoreGradePoint` varchar(50) NOT NULL,
  `scoreLetterGrade` varchar(10) NOT NULL,
  `totalScoreGradePoint` varchar(50) NOT NULL,
  `dateAdded` varchar(50) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

--
-- Dumping data for table `tblresult`
--

INSERT INTO `tblresult` (`Id`, `matricNo`, `levelId`, `semesterId`, `sessionId`, `Subjects`, `courseCode`, `courseUnit`, `score`, `scoreGradePoint`, `scoreLetterGrade`, `totalScoreGradePoint`, `dateAdded`) VALUES
(58, 'SGS129', '3', '1', '2', 'English Language', 'ENGA', '3', '5', '0', 'F', '0', '2022-08-21'),
(57, 'SGS129', '3', '1', '2', 'Mathematics', 'MATA', '3', '55', '2.75', 'BC', '8.25', '2022-08-21'),
(56, 'SGS129', '3', '1', '2', 'French', 'FRCA', '3', '5', '0', 'F', '0', '2022-08-21');

STOP making all the columns varchar.

dates should be type DATE

Numeric fields should be numeric types (int, float, decimal etc)

Sorting and comparing will fail with wrong types EG 

mysql> create temporary table test (numcol int, charcol varchar(10));
Query OK, 0 rows affected (0.92 sec)

mysql> insert into test (numcol, charcol) values (1, '1'), (5, '5'), (100, '100');
Query OK, 3 rows affected (0.05 sec)

mysql> select * from test order by numcol;
+--------+---------+
| numcol | charcol |
+--------+---------+
|      1 | 1       |
|      5 | 5       |
|    100 | 100     |
+--------+---------+

mysql> select * from test order by charcol;
+--------+---------+
| numcol | charcol |
+--------+---------+
|      1 | 1       |
|    100 | 100     |
|      5 | 5       |
+--------+---------+

mysql> SELECT 100 > 5, '100' > '5';
+---------+-------------+
| 100 > 5 | '100' > '5' |
+---------+-------------+
|       1 |           0 |    1 = true
+---------+-------------+
3 rows in set (0.00 sec)

Okay sir, I will change the data type. But hope this will solve the problem sir?
