Whichever method you choose for studying the verbs, you will find that the prefixes or endings tend to be the same in all the verb groups (with some exceptions due to ה or due to guttural letters).
So for example the FUTURE for "I", eg I will speak, I will write, I will succeed, etc, always BEGINS WITH א. in all 7 the verb the groups/binyanim . Eg:
אדבר, אכתוב, אצליח, אתפלל, אכובד, אשמר, אוזכר
Whereas the PAST for "I" I spoke, I wrote, I succeded, ENDS WITH תי in all the groups. Eg:
דיברתי, כתבתי, הצלחתי, התפללתי, כובדתי, נשמרתי, הוזכרתי
etc.
So you have to memorize these patterns. Because there are a lot of verbs, it is best not to learn too much at once.
I suggest to learn ONE group at a time, and study a few different verbs in each group.
Ask one of the fluent speakers to do exercises with you with this method, or use the Verb Park, and study one 'building' at a time.
If you are able to enter into the
http://www.hebrew-verbs.co.il/ website, I can recommend you some verb charts to memorize for each group of verbs.
Let me know if you need more clarifications, and happy studying. : )
