Leaving Cert Maths, Higher level - recommended textbook

I am due to start giving grinds in Leaving Cert Maths, Higher level. I need to brush up.

I have seen texbooks by the following authors:
- Roantree;
- OD Morris; and
- Humphrey.

I have also seen the 'Less Stress, More Success' books.

Can anyone recommended one of the above? Or something else.

When I was giving grinds I used both the "Less Stress" books and O.D Morris, Text and Tests. I found the "Less Stress" books were great for revision but if I ever needed a detailed explanation I'd just ask O.D.

I'd recommend Roantree and plenty of past paper questions. I failed my 5th year HL Maths summer exam (20%)..Had to teach myself the full course in 6th year and got a B in HL in the leaving. I put it down to doing EVERY past question at least 5 times : ) Hard work but it paid dividends!
