Beacon House quality of teaching is pathetic & most of the teachers are uninterested and give loads of home work which are not thought at all. (this is my personal teaching experience)
LGS jt branch is best & very strict! my younger brother did his a-levels in 2006 (in science) but fees is quit alot!!
city school ravi campus is good too (my younger sister completed O & A levels in business)
but in my 5 years teaching experience (private tutor part time) i prefer LACAS jt branch! fees is reasonable, quality of education is excellent,
my judgement of kids of different schools in terms of spelling mistakes, lack of concepts in doing word problems and grammatical errors, i rank the school from least to best are
beaconhouse (dull and lazy teachers, most of the teacher quit due to low pay and so syllabus is not covered in time)
LGS (i know its hard to believe but I am currently teaching 4 kids of jt branch and are very weak and lack clear concepts, gives several worksheets everyday which cannot be completed in one day!)
Rosans Islamic School (their ideology is to give tons of home works and dozens of chapters for exams which they think that student will achieve good grades but unfortunately it does not, other wise teaching quality is very good)
LACAS: students of this school are relaxed and honestly they do not require to take private tuition or extra coaching etc etc because the teachers are well qualified and expert in explaining the topics which students can understand easily. give adequate amount of homework, syllabus is completed in time! thoroughly check the students work and correct their mistakes by using sticky notes to redo or revise it again.
all these are my personal views, I haven't studied in any of these schools as i completed my o & a levels in UAE, these facts are based on my experience of teaching students privately. I apologize in advance if i mentioned anything unethical.
