Arabic has "al" for definite words, but it doesn't have an indefinite article equivalent to a or an. The sounds p and v do not exist in standard Arabic. Words like park and bark, or fan and van, can easily get mixed up. Practice (words that sound almost identical except for one letter) and record yourself reading them to check your pronunciation. Arabic has three main vowel sounds, but English has many more subtle variations (like the difference between ship and sheep, or full and fool). Practice regular dictation by listening to native audio and writing down exactly what you hear.
Arabic sentences can sometimes drop the "to be" verb in the present tense (saying things like "the office big"). English, however, is strictly Subject, Verb, then Object and always requires the verb (The office is big). Train your brain to always look for and include the verb.
You don't need hours of studying every day, consistency matters more. Spend just 20 minutes a day, before looking at anything new, try to remember and write down yesterday’s sentences from memory. This strengthens your brain's ability to recall information. Learn to pick up just one new grammar point or rule. Create a few real, practical sentences using that new rule. Listen to a short clip of native audio and write down one or two lines of what you hear. Speak aloud, record your voice, and compare your pronunciation directly against the native speaker's audio. Depending on your schooling, you might find that your speaking confidence is stronger than your reading speed, or vice versa. Find the weak half and practice it.
English spelling can be irregular, so treat spelling as part of learning vocabulary word by word rather than relying strictly on rules.
