hi im p6 student taking psle this year my science always stuck at AL3 (70-75 marks). cannot seem to break through to AL2 or AL1 math and english im doing ok (getting AL1-2) but science is my weak point. tried many assessment books already but still cannot improve any seniors or parents know good online resources or youtube channels that explain science concepts well? especially the difficult topics like photosynthesis and electrical circuits thanks!
