Answer 1

How about -

SELECT
    ID,
    SUM(IF(Subject = '2GSLIG', Score, 0)) AS `2GSLIG`,
    SUM(IF(Subject = '3ECITI', Score, 0)) AS `3ECITI`
FROM table_score
GROUP BY ID

Answer 2

Looks like you forgot the '' around 2GSLIG and 2ECITI in your aliases

SELECT ID, [2GSLIG] AS '2GSLIG', [3ECITI] AS '3ECITI' 
FROM (SELECT ID, Subject, Score FROM table_score ) AS ps PIVOT (SUM (Score) FOR Subject IN ( [2GSLIG], [3ECITI])) AS pvt
