About grammar, there's not a lot of things that you have to learn, all you need to know is the past tense, present tense and future tense: Past tense: go >went ... work >worked ... eat >ate ... sleep >slept ,... For example: I go to school > I went to school I eat rice > I ate rice I sleep > I slept present tense: he/ she/ it > IS VERB > +ING we/ they/you > ARE VERB >+ING I >AM VERB >+ING For example: 1. he is eating (eat is a verb +ING >>> eat+ing=eating) 2. we are dancing (dance is a verb +ING >>> dance+ing= dancing) 3. I am sleeping (sleep is a verb +ING >>> sleep+ing=sleeping) *** if you look at example 2: dance with an ending is a vowel, when you add the ING into the verb, you need to the away the last vowel and then add the ING after that. >>> example: mate>> mating .... leave>> leaving ..... shake>> shaking .... play>>playing future tense: I/she/he/we/they/you/it +WILL+ a verb+ the rest of the sentence for example: I will go to ... >>>I will go to the supermarket she will work ... >>>she will work for me we will ... >>>> we will eat in the restaurant People sometimes write those word in a short way: we will >>>we'll ... she will>>>she'll ... you will >>>you'll ... I will>> I'll ... Example: I'll go to the mall she'll eat that we'll kill you it'll hit you I hope this help :3 Don't worry much about the grammar because it's not very important. Just learn the basic from above ^ :)

yes it's a very good book and many learners of English use it to learn grammar (and I'm one of them)
