Environmental Management
Despite myself doing the said, I'll suggest that you DON'T do this. Read the book and do ample papers. You have the time and energy. I didn't! -
Environmental Management
I had an A*. But, that doesn't mean anyone giving it without prep will get an A*. It depends on your general knowledge and geographic sense, a lot, in addition to the paper. -
Environmental Management
If you're dedicated, you can easily do it in 5. I did it in barely 2, but then again, any curve-ball in the exam could've taken me. -
Environmental Management
Give EM too! Read the John Pallister book within two weeks. Just skim through it, and then move on to the papers. Easiest A* you can find. -
Environmental Management
Depends what all you need to do. Nonetheless, you can. I gave it reading the summaries of each of the four chapters and then doing 2 (so 4 papers) only. Didn't have the time [started just before the exams bec. I didn't like to study EM] or the energy. It's a very, very easy subject. -

Maths, Addmaths and Statistics: Post your doubts here!
Well I took up Add Math in January of my exam year (i.e June), in the second week. I covered the entire syllabus putting in a shitload of effort by mid April. Had to miss March because of my mocks and stuff. Did 2002 to 2011 in 2 weeks alongside other subjects. I could've done them in one week...- AbbbbY

Maths, Addmaths and Statistics: Post your doubts here!
It's one of the easiest O level subjects if you have an aptitude for Math, and quite fun, actually. Practice, practice and more practice. That's it!- AbbbbY

Guide and Tips-O Levels
Yes. You can. Each section has two questions in addition to the first question IIRC. Because, I clearly remember doing culture and power + authority and Crime and Education only (that too after a paper). However, just to be safe and give yourself the benefit of choice, I'll suggest doing more...- AbbbbY

Guide and Tips-O Levels
I did all my subjects without tuitions, had 10A*s and As. A cousin did 13 without tuitions and had A*s in all. Point being, it's not like tuitions are necessary to get an A/A*. It's all in your mind. Seeing your peers take them and feel like you need them too. If someone can do it, anyone can...- AbbbbY
