Support books for Spanish GCSE

[kurlique]

I am tearing my hair out over finding a suitable book to support my DS's GCSE studies in Spanish (end of yr 10). He is dyslexic and learns better from repetition/overlearning so I need a really straightforward book of grammar rules, vocab and particularly verb tables to help his learning over the summer so that he does not lose ground (he did so massively last summer). The school text book (as with most subjects, it seems) is very jolly and has lots of exercises (with no answers) but very thin as a reference book. He has also been given a workbook to complete over the summer by school but it is a struggle without a reference text. I did French and Latin at school so, although I am willing, I am totally unskilled to support him (even armed with a Collins Spanish school dictionary) and Google translate is ridiculous! Can anyone recommend a book (or even series of books) that might offer what we are looking for? BTW the additional problem I have encountered is that some books are for American Spanish rather than European Spanish!! I know he can do BBC Bitesize etc but he really needs it on paper in front of him.
TIA

Punto por Punto is pretty old, but really excellent as a quick basic reference, ideal if you learn by straightforward repetition and working through grammar rather than 'interesting exercises'. You can get a used copy very cheap, so not much lost if it doesn't help!

Thanks Takver! I ordered it straightaway!

the collins grammar one is also excellent

I bought my DD1 some Malvern Language guides but they are more vocab based than grammar.

The Collins Easy Learning Spanish Grammar is also very good.

There is also a good on-line reference, which has a Spanish section, and is particularly useful for conjugating the different tenses of verbs.

Thanks so much for your help, I have ordered The Collins one as well... starting to think by the end of this marathon I might have picked up quite a bit of Spanish too! (Still hoping that DD goes for French though!)
